Numerical Analysis of Regenerative Cooling in Liquid Propellant Rocket Engines for Ground Testing

Nan Oo

Abstract: In liquid propellant rocket engine must be required cooling techniques for high combustion temperature during long operation. In this study propellants of liquid rocket engine for ground testing are used liquid Kerosene and gaseous oxygen and they are exploded in combustion chamber of rocket engine. The combustion gases produce high temperature and pressure that effected to destroy the inner side wall or gas-side wall and the rocket engine is burned and explosion. So, cooling system is essential for liquid propellant rocket engine. For my numerical analysis study coolant is used as water for reduced temperature of liquid propellant rocket engine walls and cooling method is regenerative cooling method. To determine the cooling efficiency or cooling temperature on gas-side wall, coolant-side wall and coolant are performed by numerical calculation.
