The reciprocating motion characteristics of nanofluid inside the piston cooling gallery
Powder Technology, 2015Abstract With the peak cylinder pressure in diesel engines steadily increasing, simply extending or modifying the cooling gallery configuration may be insufficient when power rating is above a certain level. The nanofluid with better heat transfer capacity may become a more appropriate option to improve piston cooling performance.

The flow and heat transfer characteristics of engine oil inside the piston cooling gallery
Applied Thermal Engineering, 2017Abstract The current study employed the Eulerian multiphase model and the geometry reconstruction scheme to describe the periodic flow and heat transfer processes of engine oil inside the piston cooling gallery. The effects of engine speed and oil jet velocity on the heat transfer were explored.
