the aim of this manuscript is to study the implication of aluminium-oxide nanofluid for an amphibious vehicle engine (viable on land and under water) cooling system both analytically and experimentally. to achieve this, a one-dimensional model of the engine cooling system (radiator) is considered through a computational fluid code in which the mass flow rate for a range of the coolant temperatu...

Piston scuffing is one of the destructive faults in internal combustion (IC) engines. There are different causes to make this fault that lack of lubricant is the most important one among them. The purpose of this paper is the quantitative study of the piston scuffing effects on the engine performance parameters which is a new research direction in the IC engine filed. For this reason, several e...
