Experimental Study of Static Pressure Orifice Interference

Abstract

Experiments have been performed to evaluate the measurement error in a pressure orifice of diameter of the same order as the boundary layer thickness, and to investigate the disturbance created in the flow downstream of the orifice. It is shown that for small orifice depths the downstream disturbance is small but the flow in the orifice is quite strong. For larger orifice depths the downstream disturbance increases and the measurement error tends to a constant value.
