... air scheme pressure gradients on array jet impingement cooling heat transfer performance evaluated 72 total flow conditions. Conditions included four exit air scheme mass flow ratios of (1:1), (2:1), (3:1), and (1:0), three jet to target distances ( z / D ) of 2, 3, and 4, 2 array configurations...

.... Fig. 2 Effect of number of eigenvalues on the computed temperature for a two-layer problem with jet impingement cooling on one face and convective cooling due to laminar flow on the other. Values of parameters are listed in the text: ( a ) T versus x at bottom face for different number...

...Andrew J. Onstad; Christopher J. Elkins; Robert J. Moffat; John K. Eaton Jet impingement cooling is widely used due to the very high heat transfer coefficients that are attainable. Both single and multiple jet systems can be used, however, multiple jet systems offer higher and more uniform heat...
