Abstract

The air conditioning system used in automobiles uses oil which lubricates the moving part of the compressor. Excess presence of the lubricant oil in the compressor will cause a hindrance to flow inside the condenser and evaporator which will affect the heat transfer efficiency of the system. The oil is separated at the downstream of the compressor using centrifugal/ impinging on the refrigerant gas flow. The oil exists in the form of droplets in a secondary phase. The main requirement for a good design of the phase separator is to have maximum oil separation with minimum pressure drop of the refrigerant gas. The numerical simulation is carried out using Multiphase Mixture model.
