Influence of Self-Pulsation on Atomization Characteristics of Gas-Centered Swirl Coaxial Injector

Frontiers in Energy Research, 2021
There is a lack of understanding of the spray characteristics of gas-centered swirl coaxial (GCSC) injectors during self-pulsation occurs. Therefore, the self-pulsation of a GCSC injector was investigated experimentally in this study.

Fuel Grain Configuration Adaptation for High-Regression-Rate Hybrid Propulsion Applications

Aerospace
Low regression rate is the most critical issue for the development and application of hybrid rocket motors (HRMs). Paraffin-based fuels are potential candidates for HRMs due to their high regression rates but adding polymers to improve strength results ...

Study on self-pulsation characteristics of gas centered shear coaxial injector for supercavitating underwater propulsion system

International Journal of Naval Architecture and Ocean Engineering, 2011
In order to design a shear coaxial injector of solid particles for underwater propulsion system, basic experiments on gas-liquid shear coaxial injector are necessary. In the gas-liquid coaxial injector self-pulsation usually occurs with an intense scream.
