Power production from low grade heat and waste heat does not only mitigate environmental
impact but also improve energy efficiency and reduce energy cost. The type and design of …

Electric (mechanical vapour-compression) heat pumps are acknowledged as a key
technology for heat decarbonisation, their role being evidently more significant than …

Since early publications in the late 1980s and early 1990s, the finite volume method has
been shown suitable for solid mechanics analyses. At present, there are several flavours of …

The leakage clearance have a strong impact on the performance and reliability of hydrogen
circulating pump in a fuel cell system, and the thermal deformantion is the most significant …

To improve the efficiency of the twin-screw refrigeration compressor at a high speed of about
3000 rpm, the suction arrangement was investigated in this paper. Several simplified CFD …

Heat transfer between the working fluid and machine parts within a screw compressor does
not affect its performance significantly because the thermal energy dissipation is usually less …

To achieve higher efficiency of twin-screw compressors for refrigeration, the non-uniform
internal pressure distribution in the rotor chamber and the flat section in the p-θ diagram …

A computational study based on unsteady Reynolds-averaged Navier–Stokes that resolves
the gas–liquid interface was performed to examine the unsteady multiphase flow in a liquid …

This paper presents a new structure of a rotary lobe pump cavity with gradually varied gap to
mitigate the magnitude and fluctuation of the radial exciting force on the rotor. The geometry …
