Further Development of the Spark Tracing Technique for Flow Visualization

Abstract

The spark tracing technique allows one to measure both steady-state and non-steady flows and reveal their characteristic features such as shock waves flow separation regions reverse-flow regions etc. Setting with precise accuracy tie interval between spark discharges and measuring distance between successive photographed images of spark-discharge channels enable one to built the flow velocity field in the flow region covering by sparks. The present study was aimed at further development of the spark tracing technique for probing flows with periodic spark discharges and an automated system for processing the flow patterns obtained by this method.
