Experimental investigations of jet flows

The paper describes two kinds of jet flows: the confined and impinging jet flow. A triaxial thermoanemometer probe with a temperature sensor was used to study the confined jet flow. The time-average analysis of data resulted in a turbulence characteristic. It allowed the estimation of the budget of turbulent heat flux. The impinging jet flow was investigated by the Particle Image Velocimetry (PIV) method together with heat transfer analysis done with a liquid crystal film.
