National University of science and Technology, commonly known by its acronym NUST, is a public research university in Pakistan. Initially, NUST was founded by the government of Pakistan in 1981 to train members of the Pakistani Armed Forces after merging established military institutes and colleges. The university was chartered in 1993. NUST is a multi-school university with its headquarters formerly located in Rawalpindi, Pakistan. In 2008, the headquarters were shifted to the newly constructed campus in Islamabad. Other campuses are situated in Karachi, Rawalpindi and Risalpur.In 2014 the university stood at 129th rank in Asian universities in the field of engineering and technology as ranked by QS World ranking. The world university rankings' results by QS World University Rankings for the session 2014-15 published on September 17, 2014 show that NUST has maintained its name in the list of Top 500 universities. This year, NUST has also been ranked 398th in the field of Engineering and Technology among the world's top universities that participated. Scimago Institution Rankings has ranked NUST 280th in the world for Innovative Knowledge and 358th globally for Technological Impact. The university is co-educational, established to promote higher scientific education in the country especially in the field of science and technology. It offers undergraduate and postgraduate degrees leading to Ph.D in the fields of engineering, information technology, medical science, and management science. NUST is affiliated with Pakistan Engineering Council and Higher Education Commission Pakistan. Wikipedia.

In this paper Cattaneo-Christov heat flux model is used to investigate the rotating flow of viscoelastic fluid bounded by a stretching surface. This model is a modified version of the classical Fourier's law that takes into account the interesting aspect of thermal relaxation time. The boundary layer equations are first modeled and then reduced to self-similar forms via similarity approach. Both analytical and numerical solutions are obtained and found in excellent agreement. Our computations reveal that velocity is inversely proportional to the viscoelastic fluid parameter. Further fluid temperature has inverse relationship with the relaxation time for heat flux and with the Prandtl number. Present consideration even in the case of Newtonian fluid does not yet exist in the literature. © 2015 Author(s). Source

Solar cookers may be generally classified into direct and indirect types. The direct types include the box type and parabolic type, while the indirect types include the vacuum tube based cookers. This paper reviews the gradual progress made in the second type. The energy and exergy analysis of a single vacuum tube based prototype has been carried out experimentally. Performance parameters indicate a high peak exergy power of 55.6 W, while the temperature difference gap at half power is 38.75 K and the quality factor is 0.042. The energy efficiency of the cooker is 20-30%, while the exergy efficiency is 4-6%. These results make this compact single family solar cooker comparable in performance to large community based Scheffer type solar cookers. Results have been compared to a number of other solar cooker types. © 2014 Elsevier Ltd. Source

Pakistan is the sixth most populous country of the world comprising 2.56% of the total global population. However, it ranks 37th in the energy consumption, at 0.37% of the world total. The per capita energy availability is only 43 W, which is 1/7th of the world average. The greatest reason for such a huge energy deficiency is its heavy dependence on imported oil for power generation. The country is however, rich in renewable energy sources and has vast potential for their exploitation. In this article, a survey of the availability of various renewable energy sources, including hydel, solar, wind and biomass, and their current and future penetration prospects in the total energy mix have been carried out, with some recommendations. It is estimated that Pakistan has the feasible potential of 30 GW of installed power capacity from hydel and 50 GW of installed capacity from wind by 2030. © 2013 Elsevier Ltd. All rights reserved.

Peristaltic flow genre is rummage-sale to study the flow movement and heat transmission of carbonano tubes in an disproportionate canal in the occurrence of magnetic field. This is the first paper on the peristaltic flow of carbon nanotubes (CNTs) in an asymmetric channel. Two kinds of carbon nanotubes, namely, "single- and multi-wall carbon nanotubes" are used with water as base fluids. The pragmatic associations are recycled for the thermo-physical possessions of CNTs in relations of the "solid volume fraction" of CNTs. The prevailing equivalences are abridged using "long wavelength and low Reynolds number approximation." Exact elucidations have been assessed for "velocity, pressure gradient, the solid volume fraction of the CNTs and temperature profile." The possessions of numerous flow limitations, i.e., "Hatmann number M, the solid volume fraction of the nanoparticles φ Grashof number G and Prandtl number Pr " are presented explicitly for both "single- (SWCNT) and multi-wall carbon nanotubes (MWCNT)."

In the present article copper nanoparticles for the peristaltic flow in two tubes (endoscope) are discussed is discussed. The copper nanoparticles in the peristaltic literature with water as base fluid is not explored upto yet. The equations for the Cu-water nanofluid are formulated first time in literature and simplified under the long wavelength and small Reynolds quantity suppositions. Numerical elucidations have been conceded out for "velocity, pressure gradient, the solid volume fraction of the nanoparticles and temperature profile." Inspirations of numerous flow constraints on the flow and heat transmission physiognomies are developed. © 2014 American Scientific Publishers. Source
