Abstracts:

The purpose of work is experimental research of non-stationary heat exchange in an impinging jet, accumulating on the heated surface, with the presence of large-scale structures and that can be torn off flows, and also the search of possible mechanisms of heat exchange management by bringing external indignations in a stream. The cycle of experiments is in-process conducted on research of axisymmetrical stream, accumulating normally on the heated surface. A stream was both in natural terms at the different modes of expiration and at external excitation on different frequencies and amplitudes. The instantaneous and middle fields of speed and temperature are measured in near the wall part of stream by the methods of PIV and PLIF.
