Abstract:

INTEREST IN TECHNIQUES OF COOLING THE PISTONS OF HIGHLY SUPERCHARGED RECIPROCATING INTERNAL COMBUSTION ENGINES HAS REVEALED THE NEED FOR BASIC DESIGN INFORMATION RELATING TO HEAT TRANSFER IN A HOLLOW OSCILLATING PISTON PARTIALLY FILLED WITH A LIQUID. The term cocktail shaker heat transfer is used as a descriptive abbreviation.Analyses based on a conduction model and on a convection model for the heat transfer are developed to identify the governing nondimensional parameters. Experimental data supports the conclusion that a convective mechanism of heat transfer predominates. Four nondimensional parameters provide a basis for correlation of the data. Up to the present, the data obtained covers a Prandtl Number range 5 to 1500. Experiments for a Prandtl Number range much less than one corresponding to liquid metals are to be accomplished next.
