Conjugate Heat Transfer Study of Two-Dimensional Laminar Incompressible Offset Jet Flows

ABSTRACT Steady-state conjugate heat transfer study of a slab and fluid is carried out for a two-dimensional laminar incompressible offset jet. The unsteady stream function–vorticity formulation is used to solve the governing equations. The energy equation in the fluid and the conduction equation in the solid are solved simultaneously. The conjugate heat transfer characteristics are studied with four parameters, Re, Pr, S/h, and k. The fluid properties affect the heat transfer in the solid slab. The conjugate interface temperature is decreased up to the recirculation region and further increased to a developed condition. As the k is increased, its effect on Nu is reduced. Variation of local Nusselt number and average Nu are reported in detail.
