EXPERIMENTAL MEASUREMENTS OF TURBULENT PROPERTIES IN A BOUNDARY LAYER WITH BLOWING

Simultaneous measurements of temperature and velocity in a bi-dimensional turbulent boundary layer of a hot flow above a porous plate, and submitted to blowing, are performed. Two different probes, a hot wire X-array and a cold wire are used. A new combined velocity and temperature calibration process, for the hot wire probe, has been developed and validated. The mean part and the fluctuating part of the two velocity components and of the temperature are determined when they are submitted to blowing.
