Finite Element Analysis of different shape slotted orifice Plate

The slotted orifice meter is one such version of the standard design found to be better performing by several researchers. Slotted design was reported to be substantially less sensitive to upstream flow conditions and generating a smaller permanent head loss compared to the standard orifice with the same beta ratio. Static pressure recovery was also found to be faster than the standard orifice. Thus, in the present work a CFD simulation for comparison and analysing the effect of different design of slots for the metering characteristics of slotted orifice plate. An attempts has been made to simulate the flow pattern for orifice with the help of Computational Fluid Dynamics (CFD). Different slot shape has been considered for the analysis. The discharge coefficient, pressure drop, turbulent kinetic energy, turbulent eddy dissipation rate and velocity are the prime considered parameters for the comparison.
