Abstract: Although the thermal buckling problem of functionally gradient material (FGM) cylindrical shells has been investigated for many years, its theoretical solution is rarely reported when considering the material properties ...

Abstract: The gas wave ejector (GWE) is an efficient gas wave equipment using pressure waves to realize energy exchange. In this paper, a theoretical analysis of the limitation of application range and the factors affecting the ...

Abstract: The wave rotor refrigerator (WRR) is an efficient refrigeration technology. For the purpose of investigating the gas wave characteristics inside the rotor channels of WRR device, the performance and pressure monitoring ...

Abstract: Actual formation and intensity of shock wave generated during gradual opening and closure between each port and passages of wave rotor are studied by means of experiment and computational fluid dynamics simulation. The ...

Abstract: The performance of a wave rotor refrigerator (WRR) is strongly affected by unsteady heat transfer between gas and tubes. In this work, the mechanism of the heat transfer and its effects on WRR were investigated numerically ...

Abstract: As a novel generation of rotary thermal separators, a wave rotor refrigerator (WRR) is an unsteady flow device used for refrigeration in whose passages pressured streams directly contact and ...

Abstract: Pressure oscillating tubes are core components of the gas wave refrigerator. The reverse compression waves will limit refrigeration efficiency by reheat cooling gas. The promotion from traditional rotation gas wave ...
