Abstract

A simulated set up of high-speed simulated exhaust muzzle flow field is made up.Moir deflectometry is used to display and quantitatively measure jet flow field of bi-based power muzzle.The system consists of laser source,Moir deflectometer,CCD,monitor,image store and processor and 586 computer.Using Moir deflectometry and tomography the distribution of temperature of flow field is visualized and calculated quantitatively.
