The Influence of Gas Models on Numerical Simulations of Cryogenic Flow
Aerospace, 2023 At cryogenic temperatures, gases exhibit significant deviations from ideal behaviour, and the commonly employed gas model may inadequately represent the thermodynamic properties of cryogenic gases, subsequently impacting numerical simulations using ...

Numerical Study of Pressure Fluctuation and Unsteady Flow in a Centrifugal Pump
Processes, 2019 A pump is one of the most important machines in the processes and flow systems. The operation of multistage centrifugal pumps could generate pressure fluctuations and instabilities that may be detrimental to the performance and integrity of the pump.
