Abstract

This paper deals with Computational Fluid Dynamic (CFD) analysis of 3D model of an SSHE is developed in order to study the fluid flow and heat transfer with a steady state laminar, non-isothermal flow of pure glycerine, which can be treated as a newtonian fluid. The variation of the local heat transfer coefficient based on the inner wall temperature and bulk fluid temperature as a function of the main process parameters, namely, rotational Reynolds number (Rerot), axial Reynolds number (Reaxi) and dimensionless clearance, is obtained. The results have shown that viscous dissipation has a significant effect on the cooling of glycerine. The local heat transfer coefficient increases slightly when the tip clearance increases. Larger increases of the same occurred with higher rotational Reynolds number and axial Reynolds number. A correlation of the average Nusselt number is obtained in terms of the rotational and axial Reynolds numbers. This is expected to be useful in the design of SSH...
