Development and Validation of a Numerical Model of Fouling within Spiral-Grooved Tubes

Abstract: Fouling of heat transfer surfaces causes serious technical and economic problems in industry. A CFD based model is proposed for predicting fouling process in spiral-grooved tubes. This model considered both crystallization at heat transfer surface and deposition of crystal forming in the stream. The precision of this model was validated using experiment date. It was proved that the model developed in this work can predict fouling process in spiral-grooved tubes well.

“…We carried a series of experiments on the fouling characteristics of spirally grooved tubes heating transfer surface to investigate the regularity of how the geometric parameters of spirally grooved tube have great effect of fouling. The writer proposed the mass and heat transfer model of the fouling on the surface of the grooved tubes [5]. According to the model, we simulate and analyze the rules of how the groove depth and groove screw pitch of spirally grooved tube have great effect on fouling.…”
