Experimental and Numerical Investigation of the Multiphase Flow and Heat Transfer in an Oil Jet Cooled Engine Piston

ABSTRACT

The piston temperature has to be carefully controlled to achieve effective and efficient thermal management in the internal combustion engines. One of the common
methods to cool piston is by injecting oil from the crankcase underside to the piston under-crown area. In the present study, a novel 3-D multiphase thermal-fluid coupled model was developed using the commercial CFD software Simerics-MP+ to study the piston cooling using the oil jet. In this model, an algorithm was proposed to couple the fluid and solid computation domain to account for the different timescale of heat transfer in the fluid and solid due to the high thermal inertia of the solid piston.
