“…The research results showed that the well-known criterion equation for the case of liquid flow over the flat plate does not correctly describe the heat-mass transfer processes within the contact stage. The classical equation for determining the average heat transfer coefficient at turbulent air flow regime is the following [11,12] Heat and mass transfer in the thermal control system of technical and technological energy equipment…”

One of the ways of intensifying the heat and mass transfer processes in gas-fluid systems is designing jet-film contact devices with a developed surface of phase contact at high flow velocities. A contact jet-film device has been developed. The results of numerical investigation of the operation of this device are presented. There were determined the coefficients of heat transfer to the air from the surface of liquid inside of the drain cup of contact device. The criterion equations of convective heat transfer for engineering calculations of jet-film contact devices is corrected.

Abstract.One of the methods of solving the problem of improvement of heat-mass efficiency of thermal deaerators of TPSs is application of jetfilm contact devices for interaction of vapor and liquid flows. The design of these devices has been studied. Estimate calculations of hydraulic resistance have been carried out. We have obtained the equation for calculation of resistance coefficient, depending on the height of element of contact device.
