Liquid Propellants Combustion topics include: Liquid propellants combustion process, instability, analysis and simulation. Liquid propellant combustion occurs when a fuel-rich gas reacts with vapor from an oxidizer drop, forming a spherical flame. The rate of combustion increases with temperature and pressure in the combustion chamber. - Liquid-propellant rocket engines use tanks outside the combustion chamber to store their propellant. - Most liquid-propellant engines use a liquid fuel and a liquid oxidizer. - Pumps transfer the propellants from their respective tanks, increasing the...
