Effect of Different Parameters on Energy Loss Coefficient of Square Edged Orifice Plate

Chirag R. Sanghani, Dharmesh C. Jayani

Abstract


Orifice meter is a differential pressure type flow measuring device in which energy loss is a major problem. The energy loss coefficient is an important indicator of energy dissipation. In this paper, different parameters like contraction ratio, orifice plate thickness and Reynolds number were analyzed by numerical simulations using Ansys CFX 15.0 software for their effects on energy dissipation. Results of simulations revealed that, Reynolds number has negligible effect on energy loss coefficient when it is in the range of 0.5x105 to 100x105. With increasing thickness of orifice plate, the energy loss coefficient decreases slightly while it decreases with increase in contraction ratio.
