In the present paper, a numerical fluid flow and induced stresses are studied for single hole and multi-hole orifice plates. Three multi hole configurations are studied; orifice with 3 holes, 5 holes and 7 holes. Turbulence characteristics behind each configuration are analyzed and orifice geometry strength and safety factor are assessed. The multi-hole orifice showed promising results in reducing the turbulence which would increase the system reliability and performance. On the other hand, multi-hole orifice showed weaker strength for same orifice plate thickness and higher probability for pipe wall erosion.
