Wall Pressure Measurements in a Y-Junction at Pulsating Flow using Polymer/Ceramic Pressure Sensitive Paint

Abstract

Abstract In this experiment ruthenium based polymer/ceramic pressure sensitive paint (PC-PSP) has been used to study the pressure inside a y-junction at pulsating flow conditions. Pressure has been measured using the intensity based method and through phase locked averages. The aim has been to investigate the potential of PC-PSP at mass flows and pulse frequencies typical of those in the exhaust manifold of internal combustion engines
