On account of growing civilization in the developed and developing countries, use of transport becomes part of life and its population is becoming 2 to 3 times in every 5-7 years. Thus transport sector alone, is causing a faster consumption of hydrocarbon fuel and releases heavy tail pipe emissions, thereby billion tonnes of excessive carbon dioxide is added in the atmosphere every day. This is causing a serious threat to the global warming. Also the fuel reserves are depleting very fast. In 1956, the Marion King Hubbert a noted geophysicist predicted that US Fuel reserves may peak by 1975 and fuel crisis will be noticed by 1995. Thereafter in 2003, Aleklett and Campbell expressed their views that most of the countries will pass through peak oil days by 2010-12 and fuel consumption will reach to 80% by 2020-30 with the current rate of consumption. In view of growing challenges, researches are continued to supplement the energy by renewable resources and alternate energy to sustain green house hydrocarbon fuel. The major thrust is being given to explore wind energy, hydro-power, tidal and nuclear power generation. Efforts are also being made for storage of the clean energy by conversion system and its better utilization. This paper describes especially conversion system of atmospheric air proposed to be compressed by alternative energy sources like wind, solar energy etc. or disaster energy sources and stored in energy storage system. Such energy can be reused as clean energy source for running domestic appliances and light vehicles as zero pollution fuel source and ultimately check the global warming issue up to some extent. © 2010 IEEE.

This article describes a new concept of compressed air energy storage system using atmospheric air at ambient temperature as a power source for running zero pollution vehicle (ZPV) such as a motorcycle. The proposed air turbine transforms the energy of the compressed air into shaft work. The mathematical modeling and performance evaluation of a small capacity compressed air driven vaned type novel air turbine is presented here. The effect of isobaric admission and adiabatic expansion of high pressure air for different vane numbers to rotor-casing diameter ratios have been considered and analyzed. It is found that the shaft work output is optimum for some typical values of number of vanes at particular rotor-casing diameter ratios. In this study, the casing diameter is considered 50, 100 and 150 mm and rotor to casing diameter ratios are varied from 0.95 to 0.55 and vane numbers from 4 - 12 and the air turbine is found to develop maximum power to the order of 1.3, 5.3 (7.1 HP) and 11.9 kW respectively where 5.3 kW power developed with casing diameter 100 mm is sufficient to run motorcycles. © 2010 Academic Journals.

This paper describes new results towards performance evaluations of a compressed air driven vane type rotary novel air turbine/engine. The compressed air has potential of becoming nearly zero pollution power source for running the prime-mover/engine of the small bikes/motorbikes. The proposed air turbine will transform the energy of compressed air into mechanical shaft work in place of the internal combustion engine. The effect of isobaric admission and adiabatic expansion of high pressure air for different rotor to casing diameter ratios at optimum injection and vane angles are considered in the mathematical model presented in this paper. The results are evaluated with optimal vane angles, injection angles, different rotor/casing ratios, and different casing diameters. It is seen that the power output is optimum to the typical values of rotor/casing diameter ratios (d/D). In this study, the maximum power outputs for linear expansion (i.e., for minimum air consumptions) are obtained as 3.98 kW (5.41 HP) at d/D = 0.70, 5.50 kW (7.48 HP) at d/D = 0.80, and 6.08 kW (8.27 HP) at d/D = 0.85 when casing diameters (D) are 100 mm, 150 mm, and 200 mm, respectively, at injection pressure 90 psi (6 bar) and speed of rotation 2500 rpm. © 2011 American Institute of Physics.

This study describes new results of the performance evaluations of an air powered vane type rotary novel air turbine/engine. The mathematical model with different parametric values such as; different rotor to casing diameter (d/D) ratios at optimum vane angle of 45° and injection angle of 45°, have been considered and analyzed. The optimum power output is obtained at some typical values of rotor/casing diameter ratios without consumptions of excessive air. The study shows that the optimum power developed under such conditions would be 4.3-5.5 kW (5.84-7.47 HP) at linear expansion (without excessive air consumption) when d/D ratios are between 0.85 to 0.80 and casing diameter is kept 150 mm, injection pressure as 6 bar (90 psi) and speed of rotation as 2500 rpm. This power output is enough to drive any motorbike or light vehicle. © Maxwell Scientific Organization, 2011.

Globally faster consumption of hydrocarbon fuel in the transport sector is posing threat to environmental and ecological imbalances and thereby depletion of hydro-carbon fuel is causing another challenge to oil reserves. In view of these issues extensive researches are being carried out to explore the alternative energy source and or to find out appropriate energy conversion system. The atmospheric air once compressed, it is found as potential working fluid to produce shaft work for an air turbine and releases almost zero pollution in the environment. This paper details the mathematical modeling of a small capacity compressed air driven novel multi-vanes type air turbine. Effect of expansion of high pressure air collected between two consecutive vanes at different vane angles and varying inlet pressure have been analyzed here. The study shows that the total shaft power is found optimum at injection angle 60° when vane angle Θ=36° (10 vanes) and it reduces at injection angle 45° when vane angle Θ=51.4° (7 vanes) and further goes down at injection angle 30° when vane angle Θ=60°-72° (6-5 vanes), for injection pressure 6 bar and speed of rotation 2500 rpm.

Worldwide conventional resources of fossil fuel are depleting very fast due to large scale increase in use of transport vehicles every year, therefore consumption rate of oil in transport sector alone has gone very high. In view of this, the major thrust has now been laid upon the search of alternative energy source and also for cost effective energy conversion system. The air converted into compressed form by non conventional or conventional methods can be utilized as potential working fluid for producing shaft work in the air turbine and thus offering the capability of being a zero pollution energy source. This paper deals with the mathematical modeling and performance evaluation of a small capacity compressed air driven vaned type novel air turbine. Effect of expansion action and steady flow work in the air turbine at high admission air pressure of 6 bar, for varying injection to vane angles ratios 0.2-1.6, at the interval of 0.2 and at different vane angles such as 30°, 45°, 51.4°, 60°, 72°, 90°, and 120° for 12, 8, 7, 6, 5, 4 and 3 vanes respectively at speed of rotation 2500 rpm, has been quantified and analyzed here. Study shows that the expansion power has major contribution to total power, whereas the contribution of flow work output has been found varying only up to 19.4%. It is also concluded that for variation of injection to vane angle ratios from 0.2 to 1.2, the optimal power output is seen at vane angle 90° (4 vanes) and for 1.4 to 1.6 ratios, the optimal total power is observed at vane angle 72° (5 vanes). Thus in the vaned type novel air turbine the optimum shaft power output is developed when rotor contains 4-5 vanes for almost all situations of injection to vane angle ratios from 0.2 to 1.6.

This paper deals with new concept of using compressed atmospheric air as a zero pollution power source for running motorbikes. The motorbike is equipped with an air turbine in place of an internal combustion engine, and transforms the energy of the compressed air into shaft work. The mathematical modeling and performance evaluation of a small capacity compressed air driven vaned type novel air turbine is presented in this paper. The effect of isobaric admission and adiabatic expansion of high pressure air for different rotor to casing diameter ratios with respect to different vane angles (number of vanes) have been considered and analyzed. It is found that the shaft work output is optimum for some typical values of rotor/casing diameter ratios at a particular value of vane angle (no. of vanes). In this study, the maximum power is obtained as 4.5kW - 5.3kW (5.5-6.25 HP) when casing diameter is taken 100 mm, and rotor to casing diameter ratios are kept from 0.65 to 0.55. This value of output is sufficient to run motorbike.

This paper presents a new concept of the air engine using compressed air as the potential power source for motorbikes, in place of an internal combustion engine. The motorbike is proposed to be equipped with an air engine, which transforms the energy of the compressed air into mechanical motion energy. A mathematical model is presented here, and performance evaluation is carried out on an air-powered novel air turbine engine. The maximum power output is obtained as 3.977kW (5.50HP) at the different rotor to casing diameter ratios, optimal injection angle 60, vane angle 45 for linear expansion (i.e., at minimum air consumption) when the casing diameter is kept 100mm, at injection pressure 6 bar (90psi) and speed of rotation 2500rpm. A prototype air engine is built and tested in the laboratory. The experimental results are also seen much closer to the analytical values, and the performance efficiencies are recorded around 70 to 95 at the speed of rotation 2500-3000rpm.

Faster consumption of hydrocarbon fuel in the transport sector is posing global threat of depletion of fossil fuel reserves. Studies are being extensively done to search for an alternative energy source and/or to find out appropriate energy conversion system. Among various alternatives, the use of compressed atmospheric air in air turbine is an attractive option provided the atmospheric air is compressed by natural sources such as sun energy, wind energy, etc. It has the capability to produce shaft work with almost zero pollution in the environment. This paper details the mathematical modeling of a small capacity compressed air driven multivane air turbine. The effect of having different vane angles and inlet pressure on shaft work output has been studied and analyzed here. The study shows that the flow work has significant contribution in total work output and varies from 1.5% to 16.3% at different pressures, 2-6 bars, and injection angles, 30°-60°. The total shaft work is found to be maximum at vane angle θ=36° (ten vanes) when injection angle is kept at 60°, and it reduces at vane angle θ=45° (eight vanes) when injection angle is kept at 45° and further goes down at vane angle θ=60° (six vanes) when injection angle is 30°, if injection pressure is maintained at 6 bars and speed of rotation at 2500 rpm. © 2010 American Institute of Physics.
