Thermal Transfer Boundary Condition and Thermal Load of Piston for Torpedo Cam Engines

Abstract:

Piston of cam engines for torpedo works in terrible condition and always be caused fatigue breakdown by thermal load. In this paper, the thermal boundary condition of different piston parts are ascertained, such as the crown surface of piston and high-temp gas, the side of piston and cooling water, and the skirt of piston and cooling oil. Then the piston’s temperature field is obtained by using the finite element analysis software. This result provides the practical reference for further improving the structure and optimizing the design of the piston. Keywords: cam engine; piston; heat-transfer coefficient; temperature field.
