Abstract To study the complex internal flow field variation and output characteristics of a variable base radius scroll expander,
this paper uses dynamic mesh techniques and computational fluid dynamics (CFD) methods to perform transient
numerical simulations of a variable base radius scroll expander. Analysis of the flow field in the working cavity
of a variable base radius scroll expander at different spindle angles and the effect of different profiles, speeds and
pressures on the output characteristics of the scroll expander. The results of the study show that due to the periodic
blocking of the inlet by the orbiting scroll, the fluid… More >
