Owing to the requirements for high performance and long life, the friction and wear problems
of rolling piston type rotary compressors have drawn much attention. Various theoretical …

Rotary compressors have been employed in heating and cooling for more than a century
and are ubiquitous in daily life but there has not been any comprehensive record of their …

This paper investigates the two-phase leakage of the flank gap in rotary compressors by
using the coupled models of compressible Reynolds equation and refrigerant-oil pair …

Piston dynamics plays a fundamental role in two critical processes related to fluid flow in
reciprocating compressors. The first is the gas leakage through the radial clearance, which …

HFC is a potential alternative refrigerant for CFC, which depletes the ozone layer. The rotary
compressor has been widely used for refrigeration and air-conditioning systems due to its …

A rotating spool compressor is a new compressor technology that was recently introduced
by Kemp et al. in 2008. To accelerate the development of the technology, a breakdown of …

This paper presents an experimental investigation of the ester oil ISO VG10/refrigerant
R134a mixture flashing flow in a 6.0 m long, 3.22 mm ID tube, which is one of the primary …

Many researchers have modeled the refrigerant's internal flank leakage in rolling piston
compressors as a convergent, divergent nozzle flow for simplicity in simulation work. To …

The refrigerant gas leakage through the radial clearance is one of the main sources of
volumetric efficiency loss in rolling piston compressors. Therefore, the understanding of the …
