In this paper reports the results of investigation of
heat transfer performance of in compression air jet impinging of
heated surface over a flat plate & pin-fin heat sink. To mimic the
computer processor of flat plate and pin fin dimensions are
120mm*75mm and pin height is 5cm and fin radius is 1cm and
L/d ratios are 5,10,15respectively. By using this simulation in
Ansys fluent software to perform the turbulent jet impingement
on a surface. The bottom surface of the plate is supply constant
heat flux and top surface of the plate is cooled by an
impingement jet of air. It has two equations are used k-w model
and shear stress transport to handle the turbulent jet. The result
of flat plate heat sink is compare the Experimental and
simulation is higher at 0.89% of experimental to compare
numerical and Nusselt is higher at 3.35% of numerical to
compare the experimental and heat transfer coefficient is higher
at 4.51% of numerical to compare the Experimental and result of
pin fin heat sink is compare the Experimental and numerical is
higher at 0.23% of experimental to compare the numerical and
Nusselt number is higher at 0.71% of numerical to compare the
experimental and heat transfer coefficient is higher at 0.88% of
numerical to compare the experimental. The effect of L/d ratios
of jet impingement over a flat plate and pin fin heat sink on the
heat transfer performance of the heated surface of investigated.
