Performance of hard water heater with vibrating heat transfer surface for water supply systems

The influence of solid surface vibrations on the performance of heat and mass transfer processes in an aqueous medium is studied. In the course of experimental investigations, a mathematical expression was obtained that makes it possible to evaluate the influence of the frequency and amplitude of surface vibrations on the performance of considered process. We developed the construction of an electric heater with a vibrating solid surface, which makes it possible to heating water with a high concentration of hardness salts.
