Modélisation de l'encrassement en régime turbulent dans un échangeur de chaleur à plaques avec un revêtement fibreux sur les parois

Abstract : A numerical study is carried out to investigate the forced convection heat transfer induced by a turbulent flow in a parallel plate channel partly filled with a porous or fibrous material. The study involves the analysis of fouling in a plate heat exchanger, represented by a parallel plate channel with a high fouling potential liquid flow in turbulent regime. The objective is to come out with a technical solution that relies on the use of fibrous materials capability to capture deposited particles, and therefore to reduce the fouling impacts within heat exchangers. This solution focuses on reducing the fouling resistance on wall surfaces by modifying the thermal properties of the deposit. The deposit thickness evolution is obtained through a kinetics model of fouling, which is coupled to the conservation equations. An effective thermal conduction model (liquid, deposit, porous material) is selected in order to account for fouling within the porous matrix. The benefits of porous material on heat exchanger performance are analyzed
