Bipropellant combustion in a liquid rocket combustion chamber
Journal of Propulsion and Power, 1992A 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.

Gasoline Engine Combustion—Turbulence and the Combustion Chamber
SAE Technical Paper Series, 1981A research programme has been carried out to investigate the effects of operating gasoline engines with different combustion systems. The results showed that at high compression ratios (13:1) compact combustion chambers allowed an increase in compression ratio of between 1 and 2 one-half numbers for a given fuel quality compared to conventional designs.

Modeling and Simulation of Combustion Chamber [PDF]
Applied Mechanics and Materials, 2014 The work process of oil fuel burner consists of atomization and combustion of oil. In this process, different atomization and air-distribution methods would affect the quality of combustion and then bring out problems of life-span of the burner, energy efficiency and environmental pollution.

Combustion oscillations in industrial combustion chambers
Symposium (International) on Combustion, 1969Combustion roar is a “white” noise radiated from small regions in the flame which suddenly burn. Single frequency oscillations of the simple acoustic type in the combustion chamber (“screaming”) have a frequency 500 cps upwards; Helmholtz resonator oscillations have a frequency of the order of 10 times lower and occur fairly frequently in oil- and gas ...

Stability of the combustion process in elastic combustion chambers
Journal of Applied Mechanics and Technical Physics, 1972High-frequency instability phenomena in rigid combustion chambers have been studied theoretically in [1–3]. This phenomenon is attributed to the interaction between the combustion processes and combustion-product fluctuations in the chamber. One of the possible mechanisms of formation of high-frequency instability is examined in [3], where the ...

Investigation of the loop combustion chamber
Russian Aeronautics, 2017As a result of the experimental-theoretical study of the loop (countercurrent) combustion chamber of the gas turbine engine, the data and theoretical dependences are obtained on the change in the combustion completeness and combustion temperature in various operating modes.

Combustion stability of a dispersed fuel in a combustion chamber
Journal of Engineering Physics, 1968A combustion instability criterion and an analogy with the burning of a solid propellant element are established as a result of an analysis of the behavior of the gasdynamic disturbances superimposed on the process of turbulent combustion of an atomized fuel in a one dimensional combustion chamber.

Superplastic Forming of Combustion Chamber
Applied Mechanics and Materials, 2011The major advantage of superplastic forming (SPF) technology is that it can form integral and complex components in simple operation, since it is possible to form one or more sheets of superplastic grade metal into single surface tools by relatively low gas pressure.

Internal combustion engine with a porous combustion chamber
MTZ worldwide, 2003The possibility of achieving combustion at constant temperature in an internal combustion engine by using a ceramic matrix as a porous combustion chamber has recently been under discussion. This principle promises very low emissions of NOx, hydrocarbons and soot.
