Abstrakt

The problem treated in this paper stems from the practical necessity of determining the amount of moisture carried out by the vapor from a two phase heat exchanger. A characteristic cell of a heat exchanger has been modeled. The fluid flowing through the cell has been simulated using potential flow theory. Droplets of various densities and at different entry sites have been superimposed on the fluid crossing the cell at various speeds, and the shape of the trajectories ascertained. With the nonevaporative characteristics established, the case of the evaporative droplet is introduced, and a unique set of conclusions based on both evaporative and nonevaporative cases is predicated. The capability of a droplet to escape the heat exchanger or collide with the wall based on its diameter, position, density velocity and superheat of the carrying field has been determined.
