Abstract

Total temperature measurement in exhaust stream of air breathing engines like Ramjet, Scramjet and Aircraft afterburners is a challenging task as the temperatures in such engine exhausts are above 2200K. Thermocouples for such high temperature measurement suffer from oxidation and are expensive. Optical method for this application requires high level of expertise and is expensive. Gasdynamic probe is a special type of water cooled probe and can give total temperature of the flow by measuring the flow parameters like total pressure and mass flow through the probe nozzle. The probe is very simple in construction and can be made at a low cost. This paper describes about the development of a Gasdynamic probe and calibration for probe constant for various flow parameters
