“…Wang et al (2015) found that the mean impact force coefficients from a single circular jet impinging normally onto a fixed flat surface are highly dependent on the nozzle to surface distance, but relatively insensitive to the jet Reynolds number. Kastner et al (1988) calculated the jet impingement force through the integration of the measured pressure distributions on flat plates due to an impinging jet. Page et al (1989) deduced experimentally that wall pressure distribution, reattachment angle, and reattachment radius of radial jet flow are independent of the jet Reynolds number.…”

The effect of jet Reynolds number, jet exit angle, the nozzle to surface distance, jet to jet spacing on the heat transfer, and pressure force performance from multiple impinging round jets on a moving curved surface have been numerically evaluated. Two correlations are developed and validated for the average Nu number and the pressure force coefficient and the agreement between the CFD and correlations was reasonable. The surface motion effect becomes more pronounced on the Nu number distribution for low jet Re number, high jet to jet spacing, large jet to surface distance, and angled jets. The pressure force coefficient is highly dependent on the jet to surface distance and jet angle but relatively insensitive to jet Re number and jet to jet spacing.
