Bipropellant combustion in a liquid rocket combustion chamber

Journal of Propulsion and Power, 1992
A comprehensive computer simulation code is developed for the combustion-flow analysis of a bipropellant liquid rocket engine combustor. A bipropellant group combustion model is built in the computer code to facilitate the determination of various combustion modes, including the combustion of oxidizer droplets, fuel droplets and gas mixture.

Modeling of Rocket Combustion Devices

10th AIAA/ASME Joint Thermophysics and Heat Transfer Conference, 2010
The numerical simulation of the hot-gas side within combustion devices is one important element during the development of today's rocket engines. This paper presents the Astrium hot-gas simulation tool, namely the in-house axisymmetric spray combustion code RocflamII, and shows its validation to experimental subscale data.

Analysis of hybrid rocket combustion

Acta Astronautica, 1980
Abstract The problem involving flow of a turbulent boundary layer with mass injection and combustion is studied to investigate the hydrid rocket combustion. Because of the presence of combustion, the momentum equation is coupled to the energy and species equations.

Hybrid rocket combustion study

29th Joint Propulsion Conference and Exhibit, 1993
The objectives of this study of 'pure' or 'classic' hybrids are to (1) extend our understanding of the boundary layer combustion process and the critical engineering parameters that define this process, (2) develop an up-to-date hybrid fuel combustion model, and (3) apply the model to correlate the regression rate and scaling properties of potential ...
