Hot-wire measurements in non-isothermal flows require temperature compensation or correction. One of solutions is the system of two hot-wire anemometers which enable to measure velocity and temperature in non-isothermal gas flows. The output signal come from two hot-wire anemometers operating at different overheat ratio. As the two sensors operate in a CTA mode, we get a wide range of frequency bandwidth for velocity and temperature measurements. This paper present the result of modeling and optimization of a double hot-wire anemometer system providing temperature correction of anemometric signal.
