摘要
Laboratory tests were performed to measure cooling rates of an impinging oil-jet on the underside of an automotive piston as functions of oil nozzle-to-piston surface spacing, oil pressure, oil temperature, and piston temperature. Based on these results, area-average Nusselt number correlations were derived for a Reynolds number range of 100-4500, a Prandtl number range of 90-750, and a nozzle-to-piston surface spacing range over 73-160 mm, which are within the ranges expected for oil-jet cooling of automotive pistons.
