VORTEX INTENSIFICATION OF THE HEAT EXCHANGE IN THE LAMINAR FLOWS OF AIR AND M-20 OIL AROUND CIRCULAR AND ELLIPTICAL CYLINDERS

A comparative analysis of the laminar fl ows of air and M-20 oil around a circular cylinder and an elliptical cylinder with a ratio between its semiaxes of 0.3:0.5, located at right angles to an incident fl ow, at Re = 60 has been performed. The thermal and hydrothermal effi ciencies of the vortex intensifi cation of the heat exchange in these fl ows in the case of moderate heating of the cylinders were estimated.
