Density of Kerosene Aluminium Nanofluid used for Regenerative Cooling Applications of Thrust Chambers

Abstract

Efficient cooling of thrust chamber is always remaining the key area of research due to the increase in the interest of space exploration programmes. Agencies like NASA, ISRO, SpeceX, BlueOrigin are planning to start commercial flights into the space for common people. To achieve this accuracy and safety both are required and efficient cooling of the thrust chambers is one of them as it has to handle large heat loads twice, first at the time of take-off and secondly, when the vehicle has to land on the ground. ISRO has planned to use kerosene with aluminium nanoparticles for the cooling purposes of the thrust chambers. To achieve higher accuracies, the property variations as a function of temperature and pressure are required so that point to point variation can be visualized comparatively easily. In the present work, density of kerosene and its nanofluid has been studied and in order to use this property variation directly into the simulation software, curve fitting has been done for density of the nanofluid as a function of temperature.
