Computational and Experimental Investigation on the Flow Characteristics of Small-Scale Pneumatic Solenoid Valves (original) (raw)

2003

Abstract

SUMMARY A simplified one-dimensional (1D) simulation model has been elaborated in AMESim environment, which is capable of analyzing and predicting the flow characteristics of small electropneumatic (EP) valves within a wide range of pressure ratios. The flow coefficient in the model has been identified on the basis of experiments and was compared with the Perry model. The flow coefficient values have been successfully reproduced by axisymmetric quasi-3D (Q3D) computations using the FLUENT code. A number of different geometries were analyzed to determine the correlation between the geometry and the flow coefficient.
