Development of the Techniques for Calculating Heat Transfer during Sedimentation

The article considers the problem of reducing heat transfer due to the sediment appearance on the walls of heat exchange equipment. A new sedimentation similarity criterion is proposed, taking into account its thermal and electrical nature. A technique for performing experiments with a solution and sediment is given. A new criterion equation was obtained for the conditions of natural convection of a salt solution, taking into account the salt sediment on the heat exchange surface. A technique has been developed for calculating heat transfer during the sediment formation based on a new sedimentation similarity criterion.
