Heat and mass transfer and hydrodynamics of swirling flows in axisymmetric channels

Results of studies of hydrodynamics and heat and mass transfer in axisymmetric channels with local swirling of the flow are presented in a systematic fashion. Methods (analytic and numerical) are developed for calculating the local and integral characteristics of heat and mass transfer and friction for various conditions possessing a sufficient degree of universality. Detailed data are presented on velocity and pressure fields, pulsation intensity, correlations, and local heat and mass transfer in cylindrical, convergent and divergent channels. The universal properties of the integral swirling parameter are grounded as the criterion of the hydromechanical similarity of internal swirling flows. A physically justified model of internal swirling flow in an integral form is proposed, and solutions of the system of integral relations for cases of practical importance are discussed.
