... dynamics characteristics are established. An important guideline upon the use of solar air heater with jet impingement is that a solar air heater of short length and height (jet and plate spacing), and large width should be used for high thermohydraulic performance. circular jet impingement turbulence...

... of slot width ( B ), and the effect of nozzle-to-plate spacing ( H ). Experimental determination of the local Nusselt number (Nu) by a single circular jet impingement was performed by Baugh and Shimizu [ 11 ]. They kept the target at a constant heat flux and measured the local Nu by measuring the local...
