To ensure the safety work of the bearings, the radiators were generally installed on the shafts between the circulating cooling water pump chambers and the bearings, which might reduce the working temperatures of the bearings. A heat calculation model of the shaft-radiator-bearing system was established using connected heat equilibrium calculation method herein. The heat equilibrium calculation on the shaft-bearing-radiator system was proceeded by home-made calculating program with VC language, and the temperature distribution along the axis was obtained. The influences of the radiator construction on the bearing's operating temperature were analyzed. The calculating results show that, the heat transfer of the shaft-bearing-radiator system is affected greatly as the radiator setting on the shaft, and the reduction of bearing temperatures is only slightly. Other cooling methods should be adopted such as forced-air cooling mode to increase the heat transfer ability of the bearing bracket and further reduce the temperature at the bearing and increase the reliability of the pump. © 2017, China Mechanical Engineering Magazine Office.

Radial inlets are typical upstream components of multistage centrifugal compressors. Unlike axial inlets, radial inlets generate additional flow loss and introduce flow distortions at impeller inlets. Such distortions negatively affect the aerodynamic performance of compressor stages. In this study, industrial centrifugal compressor stages with different radial inlets are investigated via numerical simulations. Two reference models were built, simulated, and compared with each original compressor stage to analyze the respective and coupling influences of flow loss and inlet distortions caused by radial inlets on the performances of the compressor stage and downstream components. Flow loss and inlet distortions are validated as the main factors through which radial inlets negatively affect compressor performance. Results indicate that flow loss inside radial inlets decreases the performance of the whole compressor stage but exerts minimal effect on downstream components. By contrast, inlet distortions induced by radial inlets negatively influence the performance of the whole compressor stage and exert significant effects on downstream components. Therefore, when optimizing radial inlets, the reduction of inlet distortions might be more effective than the reduction of flow loss. This research provides references and suggestions for the design and improvement of radial inlets. © 2016, The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.

A numerical optimization is presented to reduce the vibration and noise of a centrifugal fan volute. Minimal vibration was considered as the aim of the optimization, and the calculation of sound field induced by the vibration of the volute was only based on the final results of the optimization. After the three-dimensional unsteady flow simulation of a centrifugal fan, the parametric finite element model of the volute was created using the pressure fluctuations at blade passing frequency on the volute as external excitation forces. To validate the finite element model of the volute, natural frequencies and amplitudes of the normal velocities of the volute at blade passing frequency were measured. A good agreement was found between the numerical and the experimental results. Then, random method and first-order optimization method were applied in the optimization process. The numerical optimization of the volute was carried out using the local thickness of the volute as design variables and the quadratic sum of the nodal velocities as an objective function. Numerical optimization results show that the volute vibration is reduced by the optimization method. Finally, vibroacoustics of the volute before and after the optimization were calculated by direct boundary element method. The results show that the radiated power of the vibroacoustics of the volute is reduced significantly as well as the vibration of the volute after the optimization.This numerical optimization process provides a useful reference for vibroacoustic reduction of centrifugal compressors and centrifugal fans whose fluids should be kept strictly in a system without leakage. © 2012 Elsevier Ltd.

Variable inlet guide vanes (VIGVs) can regulate pressure ratio and mass flow at constant rotational speed in centrifugal compressors as a result of inducing a controlled prewhirl in front of impellers. Radial inlets and VIGVs are typical upstream components in front of the first-stage impellers in many industrial centrifugal compressors. However, previous investigations on VIGVs in centrifugal compressors were mostly conducted under the condition of axial inlets, and this study aims to focus on the effects of radial inlet on the VIGVs performance of a centrifugal compressor stage. The axial inlet stage model is compared with the radial inlet stage model with splitters using numerical flow simulation. The flow from the radial inlet was nonuniform in both circumferential and radial directions; thus, the VIGVs, the impeller, the vaneless diffuser, and the return vane channel are modelled with fully 360° passages. The three-dimensional (3D) flow field is numerically simulated at VIGVs setting angles ranging from -20° to 60°. The overall stage performance parameters are obtained by integrating the field quantities. Though the splitters are equipped in the radial inlet, the overall stage polytropic efficiency decreases by an average of 4 per cent and total pressure ratio decreases by an average of 3.3 per cent in comparison with the axial stage model. This can be attributed to the effect of both flow non-uniformity induced by radial inlet and flow loss in the radial inlet at different VIGV setting angles. The flow loss in the radial inlet with splitters is the main reason of the stage performance decrease compared with the flow non-uniformity. The simulation results show that the performance of VIGVs is degraded by its inlet flow distortions resulting from a radial inlet. The results in this study can be applied to centrifugal compressor design and optimization. © Authors 2011.

Beetles cuticles have delicate and complicated body structures. In this paper several models are developed based on the observation of microstructures of beetle cuticles. The analysis for capability of energy-absorbing of beetle cuticles are presented with the nonlinear finite element software ANSYS/LS-DYNA. The discussions on effects of structures and materials are provided. The structures of original models are improved to make them resemble the trabecular structure of beetle cuticles for larger energy absorptions. A comparison is carried out between the improved model and cylindrical tube in terms of static and dynamic axial impact responses. The results show that the improved model absorbs more energy and performs in more stability way than the tube. This makes it an excellent structure for the device of structural crashworthy and energy absorption.

It was previously known that C-doping in Cu effectively enhances the film thermal stability and maintains a low electrical resistivity even upon high-temperature annealing, via a diffusion inhibiting the mechanism of C-stabilized oxide interlayer between Cu and Si. In the present work, the stability and resistivity are investigated in two Cu films doped with more C, respectively 2.9. at.% and 4.2. at.% as measured by EPMA. As expected, the thermal stability is even further enhanced, without significantly affecting the resistivity. After a systematic microstructural investigation by TEM, it is revealed that the relevant mechanism lies both in the enhanced stability via C dissolution in the silica native oxide layer at the Cu/Si interface and in the C-passivated Si surface zone beneath the layer. In the 4.2% C film, the Cu/Si interaction is mainly inhibited by self-forming SiC nano-particles and the resistivity remains below 3. μΩ·cm even upon annealing at 500. °C for 40. h. The C-doping can then be a simple process route towards manufacturing stable Cu interconnects. © 2014 Elsevier B.V.

A multi-objective scheduling method based on the controlled Petri net and GA is proposed to the flexible job shop scheduling problem (FJSP). Function objectives of the proposed method are to minimize the completion time and the total expense and workload of machines. Firstly, a Parikh vector based approach for Petri net controller is introduced, and based on this method, the Petri net model is constructed for FSP with machine breaking down. Then, the genetic algorithm (GA) is applied based on the controlled Petri net model and Pareto. Finally, simulation results based on an example show that the method is efficient. © (2012) Trans Tech Publications, Switzerland.
