The effect of suction on average heat transfer coefficients between an isothermal permeable plate and impinging round jets was studied for suction velocities in the range 0.3−0.7% of the nozzle exit average velocity. Of the two identical nozzles' used, one generated an unconfined jet while the impingement flow from the second nozzle was partially confined by a 348 mm diameter plate that was structurally an extension of the nozzle plate. Two Reynolds numbers were used and the jet-to-plate spacing was varied between 2 and 10 jet diameters. For unconfined and partially confined jets, the general effect of applying moderate suction is to increase average heat transfer coefficients by roughly a constant amount, the absolute increase being larger with than without confinement.
