Study of a regenerative cooling system while using heat-conductive metal nanoparticle suspension in n-decane

The paper presents the calculation estimates for efficiency of regenerative cooling for a model cylinder-shaped flow duct using a suspension of heat-conductive metal nanoparticles in n-decane as fuel/coolant. We adapted a standard mathematical model of conjugated heat transfer that accounts for thermophysical properties of the metal nanoparticle suspension and n-decane. The data are presented for heating up the nanosuspension and the model duct walls for the cases of different content of metal nanoparticles in nanosuspension. There exists a range beneficial for heat transfer from n-decane.
