Abstract
The paper presents the calculation estimates for efficiency of regenerative cooling for a model cylinder-shaped 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 the nanosuspension and the model duct walls for the cases of different content of metal nanoparticles in nanosupension. The range where the use of nanosuspension gives advantages in terms of heat removal relative to the n-decane has been shown.
