Sinopsis

The paper deals with the research of a temperature field in a pulsatile (synthetic) jet. Precise measurement of the temperature field in moving fluids is connected with many difficulties. The temperature experiments were carried out with a constant current anemometry (CCA), which is a contact method, and were compared with the results achieved by a Mach-Zehnder type of digital holography interferometry (DHI). The velocity of heated SJ was measured using a constant temperature anemometry (CTA).
