Factors Affecting Characteristic Length of the Combustion Chamber of Liquid Propellant Rocket Engines

open access: yesMehran University Research Journal of Engineering and Technology, 2019
Optimum characteristic length of the combustion chamber of liquid rocket engine is very important to get higher energy from the liquid propellants. Characteristic length is defined by the time required for complete burning of fuel.
