.... The technique has become known as spark anemometry and offers a robust means of velocity sensing for engine combustion chambers and other high temperature environments. This paper describes an experimental study aimed at improving performance of spark anemometry as an engine research tool. Bench tests were...

... than the dynamic head. The hot-wire anemometry is a useful tool to determine turbulence even when the flow temperature varies. The method described here shows that the temperature and density changes can be compensated by considering flow temperature as a parameter in the calibration law...
