Abstract
Thermal treating of highly viscous product is associated with many problems such as fouling, an inhomogeneous treatment and burn-on of product. The efficiency of a SSHE lies behind its simple design; the rotating blades continuously scrape the film of product deposed at the heat transfer surface, thus providing a large heat transfer coefficient. The bulk mixing phenomena is purposely induced in SSHE by adopting a new arrangement of blades noted alternate blade in order to ameliorate the thermal performance within the SSHE. A three dimensional numerical simulation of the coupled hydrodynamic and thermal behavior within a conventional SSHE and an alternate blade SSHE was conducted for comparison purpose. Continuity, momentum and energy equation were solved using the finite volume ANSYSFLUENT 19.0 tool. Results of the simulation show that the new design offer a heat transfer coefficient equal to 647.55 W/m2K, around 63% higher than the heat transfer coefficient within the conventional SSHE design.
