Abstract

Due to their high thermal effectiveness, good flow distribution and ease of sanitation, PLATE HEAT EXCHANGERS (PHEs) are widely used for continuous pasteurization of liquid food products. Since most food products in this research are non Newtonian fluids, flow behavior in various chevron angles of non–Newtonian power law fluids is studied by means of 2D Computational Fluid Dynamics (CFD). For this purpose, aqueous solutions of carboxymethylcellulose (CMC) at different weight concentrations, ranging from 0.5 % to 2% and 10£Reg£300 held at a constant temperature of 20°C were considered as operating conditions. To generate geometry and mesh, solve governing equations by finite volume method and analyze CFD results, software applications Gambit 2.0 and FLUENT 6.0.12 were used respectively. Analyses over the relationship between Reynolds number, fanning FRICTION FACTOR and rheological parameters of the fluid and chevron angles of the plates for different concentrations of CMC have been performed. Predictions of CFD calculations were compared to the experimental data, and these results showed a very good agreement.
