ABSTRACT = {Conjugate heat transfer from a flat circular disk is investigated both computationally and experimentally with a constant heat flux imposed on its 
bottom surface and a shower head of air jets impinging on the top surface. The shower head consists of a central jet surrounded by four neighboring 
perimeter jets. Measured temperature data at twelve locations within the plate are compared with the conjugate heat transfer result obtained at the 
same locations computationally by Shear Stress Transport (SST) κ-ω turbulence model. The spacing to orifice diameter ratio (H/d = 1 to 4), the jet 
Reynolds number (7115 to 10674) and the plate thickness to diameter ratio (0.25, 1 and 2) are varied. Measured temperature data within the solid 
plate agrees well with the computationally obtained conjugate heat transfer result. Primary peaks of the Nusselt number at the stagnation point and 
secondary peaks at the interaction points of the wall jets are observed. Local variation of heat transfer rate with varying H/d is significant but found to 
be less sensitive to the thickness ratio. When compared with a single jet of equal mass flow rate and Reynolds number, the shower head jets provide 
more uniform temperature distribution with higher heat transfer rate.},
