Numerical Simulation of Jet Impingement Cooling on a Pin-Fin

Abstract

The study of a laminar natural convection in a domain with conjugate boundary condition is done by numerical simuation. The Bottom wall of the enclosure is considered to be isothermal. The problem is solved using Ansys Package 15 and the fluient is used for meshing the domain. Various cases are considered by varying the parameters like Reynolds number, jet-to-fin spacing, width of fin and Height of Fin to analyse their effect on the heat transfer and flow characteristics. Reynolds number is taken equal to 3078, 5019 and 8673 to constrain the flow as laminar in enclosure. The result shows some significant dependence on Reynolds number and jet-to-fin spacing in the flow and temperature field inside the domain.
