On the convection limited self-sustained acoustic vibrations in a closed cylindrical chamber
Abstract
The heat transfer rate from a constant-temperature hot wire and the vaporization rate of a liquid droplet of propellant in a rocket engine are both convection limited; therefore, a system using a hot-wire transducer as an analog of a liquid droplet of propellant was developed and used to simulate the coupling of the combustion process with the gasdynamics in liquid-propellant rocket engines. It was assumed that the combustion process was vaporization-limited and that the combustion chamber was acoustically similar to a closed-closed right-circular cylinder. The analog system was then employed to investigate the ingredients of acoustic instability of liquid propellant rocket engines.
