Abstrakt
Experimental investigations of a flat plate heat transfer in the presence of transition induced by wakes after still and hesitating cylinder were carried out. Analysis of distributions of local heat transfer coefficients, temperature and velocity profiles, their fluctuations and other characteristics of boundary layers permits to determine the length of wake-induced transition and its location. On the basis of study of wakes characteristics in the free-stream the reason of heat transfer intensification in pre-transitional boundary layer was determined. Under influence of periodic unsteady wakes transition region shits upstream in comparison with the case of steady wake.
