Abstract

Abstract

In order to study the fouling caused by the crystallization deposition of CaSO₄ solution in the narrow rectangular channel and its effect on heat transfer, based on the reasonable fouling deposition, fouling erosion and fouling thermal resistance models, the crystallization deposition simulation calculation of fluids with certain heat flux, inlet velocity , inlet temperature and fluid concentration is carried out by using FLUENT software and user-defined function (UDF).The research results show the fouling generation of this working medium and its influence on heat transfer, and the influence of three factors, namely heat flux, inlet velocity and fluid concentration, on fouling deposition is obtained: the fouling resistance increases with the increase of heat flux, decreases with the increase of inlet velocity, and increases with the increase of fluid concentration. This study can be used to simulate the fouling deposition process in the narrow rectangular channel of plate-shaped fuel elements due to crystallization.
