Paper Abstract

A rugged optical method has been designed for making measurements in a hostile industrial environments such as the combustion exit flow ofa gas turbine engine. Typically the gas temperature in such a combustor is 1000 K and the speed of the flow 700m/s. A transient shock tube has been constructed at MET (Massachusetts Institute of Technology ). The objective being to simulate the mixing rate for different types of exit combustor exit nozzles. A direct particle visualisation approach has been developed combining a c/w Argon/ion laser and an electronically shuttered image intensifier. The combination has been used measure the density distribution average over the complete 3ms run time ofthe transient shock tube facility. The system also has the potential to measure the entrainment of the surrounding ambient air and make velocity measurements.
