Investigation of the Effect of Partial Heating in an Internally Heated Vertical Annulus

Shahid Husain, Jawed Mustafa and M Altamush Siddiqui

Numerical Analysis has been carried out for transient two dimensional heat transfer and fluid flow during natural convection of a fixed Prandtl number (0.71) fluid through an internally heated vertical annulus. The governing continuity, Navier stokes and energy equations have been solved using finite volume SIMPLER technique. The governing equations are solved on a staggered mesh. The solutions are obtained for an aspect ratio of 10 and radius ratio of 2 by varying the heating length from full to 50%. The MPI parallel programming technique was used for domain decomposition and parallelization of code. The transient behavior of the system has been discussed in detail.
