NUMERICAL SIMULATION OF FLOW INSIDE DIFFERENTIALLY HEATED ROTATING CAVITY
1. INTRODUCTION Flows inside differentially heated rotating cavity has wide range of applications in the study of geophysical and astrophysical flows as well as in practical engineering applications like manufacturing of single wafer crystal for semiconductor industries and numerous metallurgical processes. Due to rotation the heat transfer characteristic of the flow becomes complex and thereby, makes it very challenging in terms of numerical and experimental investigations. It is observed that numerical simulations of rotating cavity flows reported in literature usually model the flow in non-inertial (rotating) frame of reference, in which the effect of rotation is considered indirectly through source terms (like centrifugal, Coriolis and Euler forces) in the Navier-Stokes (NS) equations. Numerical treatment of these source terms can sometime become troublesome and tricky, and it remains an area of research till date. We, therefore, consider mathematical modelling of the differentially heated rotating cavity problem in inertial frame of reference in order to avoid the above source terms. In the later case, the rotation of the cavity directly influence the flow and heat transfer phenomena inside it as in the real situation.
