Orifice plates are most commonly used to measure flow rates in pipes, when the fluid is single-phase (rather than being a mixture of gases and liquids, or of liquids and solids) and well-mixed, the flow is continuous rather than pulsating, the fluid occupies the entire pipe (precluding silt or trapped gas), the flow profile is even and well-developed and the fluid and flow rate meet certain other conditions. Under these circumstances and when the orifice plate is constructed and instal… WebJun 1, 2024 · The fluid flow through a single hole orifice plate and multi holes orifice plate were analyzed in this paper by using Computational Fluid Dynamics (CFD).
