Influence of suction muffler design on the suction effective flow and force areas of a reciprocating compressor.

Number: 1132

Author(s) : RODRIGUES T. T.

Summary

The concept of effective flow and force areas is commonly used to evaluate the performance of the suction and discharge processes in reciprocating compressors, which is strongly dependent on the flow head loss through the orifice-valve pair. The typical approach considers uniform and homogeneous flow at the port inlet. However, for the suction process, the suction muffler disturbs the flow patterns towards the orifice generating, for instance, recirculation structures. This work studies the effect of the suction muffler in the effective flow and force areas during the suction process of a reciprocating compressor. A CFD model is applied for this purpose. The results show that the suction muffler must be taken into consideration when evaluating both effective areas. The analysis also indicates that the optimization of the suction effective areas can be obtained by redesigning the suction muffler rather than the suction port and the valve.
