FLOW MEASUREMENT WITH TEMPERATURE-SENSITIVE PAINT (TSP)

Kurzfassung

The course gies a basic introduction to Temperature Sensitive Paint (TSP). It consists of a lecture explaining basic theory and a demonstration of simple experiments. Surface temperature distribution and heat transfer on test bodies can be determined with the help of TSP, which is a well known method for two-dimensional temperature measurement. A specific measurement technique based on the use of TSP enables us to visualize for example the laminar-to-turbulent boundary-layer transition on wind tunnel models. Stationary measurement are possible in hypersonics, tranic and low-speed conditions alike. Measurement can also be performed on rapidly rotating propellers or rotors. Transient measurement at frwquencies of up to 10 kilohertz are also possible in transonic flows.
