Comparative efficiency of several methods for the intensification of heat transfer in the case of longitudinal flow past a cylinder

The paper describes a heat transfer intensification method which relies on the augmentation of the degree of turbulence by a cyclone chamber and the fragmentation of the flow into a system of impinging jets. It is shown that in the case of impinging jets the average heat transfer from the surface of the cylinder is nearly twice as high as for air pumping at equal power losses. Distributions of local heat transfer coefficients and empirical relationships for the calculation of average heat transfer are presented.
