Experimental Determination of the Heat Transfer Coefficient in Piston Cooling Galleries
SAE Technical Paper Series, 2018 <div class="section abstract"><div class="htmlview paragraph">Piston cooling galleries are critical for the pistons’ capability to handle increasing power density while maintaining the same level of durability. However, piston cooling also accounts for a considerable amount of heat rejection and parasitic losses. Knowing the distribution of

Controllable thermal state design method of flexible shapes of piston cooling galleries
Applied Thermal Engineering, 2021Abstract The uneven temperature field is a great contributor to abnormal deformations and local damages of the piston. The piston gallery cooling is one of the effective ways to achieve an acceptable temperature field of the piston head. However, the traditional design of piston cooling gallery cannot accurately control the local thermal state of the
