Abstract:

A technique for measuring static temperatures in shock tunnel flows is described. It is based on the electronic excitation of nitrogen molecules by a beam of high energy electrons. The resulting spontaneous emisaion or electroluminescence has a spectral intensity distribution that can be related to the gas static temperature. A method has been devised to measure this intensity distribution during the short test time available in a shock tunnel. From such a measurement the gas temperature can be deduced by the methods outlined in the text. The technique has been used to make a number of temperature measurements in a shock tunnel. Some of these are reported for illustrative purposes. Author
