Due to the current global energy shortage and increasingly serious environmental issues,
green propellants are attracting more attention. In particular, the ammonium dinitramide …

Impinging-jet injectors, liquid–liquid coaxial swirl injectors, and liquid–liquid pintle injectors
are representative liquid–liquid injectors in liquid rocket engines (LRE). For these liquid …

Combustion characteristics such as combustion performance and combustion stability have
been studied experimentally using a small liquid rocket thrust chamber with 19 liquid–liquid …

An experimental investigation is performed to explore the characteristics of sprays produced
by a liquid–liquid coaxial swirl injector in a non-combusting environment. Phase Doppler …

FAST atomization, uniform mass distribution, and mixing of propellants have great influence
on combustion efficiency in liquid rocket engines. The injector is an essential device in the …

Experimental investigations on the self-pulsation dynamics in a gas-centered swirl coaxial
atomizer are conducted using water and air. Experiments are performed in the pulsation …

An experimental study is performed to study the effect of inner and outer injection pressure
on spray characteristics and the detailed structure of interacted liquid sheets of a coaxial …

A LIQUID rocket engine (LRE) requires a propellant supply system. Propellants can be
supplied by a turbopump or a propellant tank pressurized with inert gas. A turbopump …

Dual-orifice atomizers have been developed to overcome the limitations of simplex
atomizers—where “simplex” refers to having only a single flow channel—which cannot …

An experimental study has been performed to investigate the effects of the recess length on
the discharge coefficients of swirl coaxial injectors. Liquid oxygen and kerosene (Jet A-1) …
