HEAT AND MASS TRANSFER UNDER COOLING OF FLOWING WATER SHEETS BY AN AIR COUNTERFLOW
V. M. Sobin and G. V. Dashkov UDC 536.423 On the basis of the system of differential equations in partial derivatives, the boundary-value problem of heat and mass transfer under cooling of flowing water sheets by a turbulent air counterflow has been formulated. Its approximate analytical solution is given. From the point of view of the accepted model of interaction of flows, it has been shown that the obtained theoretical values of the heat and mass transfer coefficients are in good agreement with the experiment.
