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

A contribution to film coefficient estimation in piston cooling galleries
Experimental Thermal and Fluid Science, 2010The need to reduce fuel consumption and exhaust emissions in internal combustion engines has been drastically increased during last years. One of the most important processes affecting these parameters is heat transfer from the in-cylinder gas to the surrounding walls, as this mechanism has a direct influence on the combustion process.

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

Computational modelling of convective heat transfer in a simulated engine cooling gallery
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2007Experimental data from internal combustion (IC) engines suggests that the use of proprietary computational fluid dynamics (CFD) codes for the prediction of coolant-side heat transfer within IC engine coolant jackets often results in underprediction of the convective heat transfer coefficient. An experimental and computational study, based on a coolant
