Application of the Dorodnitsyn Transformation for Analysis of Heat and Mass Transfer in Rotating Flows

A method based on the use of the Dorodnitsyn transformation is proposed for calculating the nonisothermal laminar boundary layers on a disk rotating in a gaseous medium. An approximate account for the nonlinear inertial terms is performed by the Slezkin-Targ method. It is demonstrated that, upon cooling the surface of the disk-end rotating slower than the external flow, it is possible not only to weaken the radial flow of a viscous heat-conducting gas, but also to change the direction of the flow velocity in the boundary layer to the opposite one. The possibilities of using the results to reduce the masking effect of the end elements in the experimental study of the stability of rotational flows as well as to control the circulation flows in closed systems are discussed.
