NUMERICAL-ANALYSIS OF MIXED CONVECTION HEAT-TRANSFER OF A HIGH-VISCOSITY FLUID IN A RECTANGULAR TANK WITH ROLLING MOTION

A numerical analysis is presented for the mixed convection heat transfer of a high viscosity fluid contained in a two-dimensional rectangular tank subject to rolling motion. The study is motivated by the thermal design of heating systems of a tanker in a wavy sea. Basic equations are given for the body (tank)-fixed coordinate system considering inertia forces acting on the fluid in the tank including centrifugal force. Similarity parameters are introduced, and their influence on the heat transfer is systematically examined.
