Summary

Oversize resistance loss of gas pulsation attenuator will cause the compressor exhaust back pressure higher, increase the compressor power consumption and increase the exhaust temperature, which leads to the deterioration of the compressor operation. Therefore, proper control the pressure loss of the attenuator used in reciprocating compressor is especially important. This paper presents an investigation of the pressure loss of the Perforated Tube Attenuator (PTA). Three-dimensional computational fluid dynamics (CFD) has been used to investigate the influence of porosity, flow velocity, diameter of the holes on the pressure loss. The results showed that the pressure loss of PTA decreases with porosity increasing following nearly a hyperbolic trend, ascents according to a parabola law with the inlet velocity increasing and descents little with the hole diameter rising.
