The orifice plate is a typical obstruction type of flow meter, widely used in industries for flow measurement. ISO-5167-1 and BS1042 standards provide the value of Discharge Coefficient for both standard Orifice Plate and Quarter Circle Orifice Plate. In the present work, an attempt is made to study and develop a computational model of flow through an Orifice Plate which can be used as an efficient and easy means for predicting the compressibility effect using Computational Fluid Dynamics (CFD) software. ANSYS FLUENT-14 has been used as a tool to perform the modelling and simulation of flow through Orifice Plate. Analysis of flow through Orifice Plate has demonstrated the capability of the CFD methodology for predicting the accurately the values of Cd, ε and CPL over a wide range of operating conditions. CFD methodology also has been used to analyse the effect of various parameters like diameter ratio, Reynolds number, and pressure ratio on the performance parameters of the orifice meters. It has been demonstrated that the validated CFD methodology can be used to predict the performance parameters of orifice plate assemblies even under conditions not covered by ISO 5167-1 and BS1042 standards.
