The twin pulsed wire anemometer - A new instrument for measurements in complex flows (original) (raw)

Abstract

This paper describes the preliminary development of a new form of the standard pulsed wire anemometer, and details the initial results obtained from it. The new instrument described here differs from the pulsed wire anemometer in that the probe consists of only two wires, a sensor wire and a pulsed wire, thus creating a simpler and more compact probe with an inherently better yaw response compared to the three wire design. New electronic hardware has been designed to control the probe, which includes a relay switching circuit, which alternates the roles of the two probe wires, thus allowing the flow direction to be unambiguously defined with only two wires. The instrument is best used under program control, as part of an on-line data acquisition system.
