Numerical Simulation of Laminar Convection Heat Transfer From an in-Line Array of Discrete Sources to a Confined Rectangular Jet

Conjugate convection/conduction numerical simulations have been performed to determine flow and heat transfer phenomena associated with using a single laminar slot jet to cool a linear array of discrete heat sources. Flow is restricted to a channel formed by an impingement surface, within which the heat sources are flush mounted, and a parallel confinement surface, through which the jet is discharged. Calculations reveal a primary recirculation cell between the jet and the confining surface and, for restricted conditions, a secondary cell on the impingement surface that produces a maximum and a minimum in the distribution of the local convection coefficient. The effects of the jet velocity profile and pertinent dimensionless parameters on flow and heat transfer conditions have been calculated
