Research of the Effect of Salt Deposits on Heat Transfer during Natural Air Convection

This article studies an actual problem of a decrease in heat transfer because of the formation of a deposit on the walls of the heat transfer equipment. A new heat transfer similarity number of deposit formation that can describe its thermal and electric nature is presented here. New methods of experimental studies under free air convection with deposit on the heat transfer surface are presented and discussed. The deposit is a dense wet mass of NaCl salt. A new criterion equation for the natural air convection conditions is obtained and shown in the article. New methods for calculating the heat transfer during deposit formation based on the created heat transfer similarity number of deposit formation are developed.
