LDV measurement of flow through orifice and perforated plates and comparison with computational work
Abstract
Velocity and turbulence profiles in the neighborhood of a flow straightener/flowmeter combination are measured using laser Doppler velocimetry (LDV). The effect of nonstandard flow conditions on flowmeters is investigated. The velocity profiles for the flow straightener are analyzed. Three-dimensional turbulent flow through the orifice and perforate plates is computed using the governing elliptic partial differential equations; LDV is used to validate the computational data. It is concluded that LDV is an effective method for measuring velocity profiles in the neighborhood of flow straightener/flowmeter combinations.
