Velocity and temperature fields have been described in the wall region of a cylindrical vessel equipped with radial baffles mixed by a standard six-blade disc turbine impeller under the turbulent regime of the flow in a homogeneous Newtonian charge. The results of experiments offer conclusions regarding the mechanism of the turbulent flow in individual subregions of the wall region together with the method of description of the flow in these regions as a sequence of impinging wall turbulent streams. Based on the theory of analogy the results on the turbulent heat and momentum transfer have been compared and confirm validity of the Chilton-Colburn analogy in which the characteristic quantities for the calculation of the local friction factor are parameters of the wall region flow - the characteristic velocity and the characteristic thickness of the wall region.
