Abstract :
The conjugate heat transfer within a bottom-heated non-conventional cylindrical enclosure is important with respect to the processes in chemical and nuclear industries. In this research work numerical analysis of the enclosure with respect to the centrifuge machines used in the process industry is presented. Various CFD simulations of the experimental work of [1] are performed to study the effects of materials of the disc and inner cylinder and geometries of outer cylinder on the enclosure. Generally, a uniform temperature is required in such enclosures. A more uniform temperature is observed in the enclosure by using aluminum inner cylinder at a temperature of 433K of the bottom disc and using two different diameter outer cylinders as compared to the mild steel and stainless steel.
