COOLING EFFECTS OF "COCKTAIL SHAKER" SYSTEMS ON PISTONS

Although the cocktail shaker cooling of the piston has commonly been applied in high powered diesel engines, the evaluating method of the convective heat transfer rate between the piston surface and the cooling medium has not satisfactorily been made clear. In order to get nondimensional explanations for the convective heat transfer, this experimental study was carried out by using a test rig which was able to apply simple and basic plane surface pistons with various cavity conditions to simulate operating conditions of diesel engines. In the case of pure cocktail shaker cooled pistons (without any jet or speed cooling coexistence), the nondimensional explanation for the heat transfer was given as a straight line for various cooling mediums as engine oil, spindle oil and water, so that the mean heat transfer rate was able to be shown by a very convenient form.
