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.

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 ...

Gasoline Engine Combustion—Turbulence and the Combustion Chamber
SAE Technical Paper Series, 1981<div class="htmlview paragraph">A 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 2½ numbers for a given fuel quality ...

Combustion-Chamber Progress Correlated
SAE Technical Paper Series, 1930<div class="htmlview paragraph"><b>P</b>REVIOUS papers on Combustion-Chamber Design by three leading authorities on the subject showed enough points of real or apparent disagreement to leave the designing engineer in doubt on many of the details of design which they discussed.

The Quiescent Combustion Chamber
Journal of Fluids Engineering, 1931Abstract The term “quiescent” is originated as describing more accurately than “non-turbulent” the condition of the combustion chamber in some fuel-injection engines at the time of injection of the fuel. Such a combustion chamber is considered quiescent if the movement of the air has no appreciable effect on the distribution of the fuel ...

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.

Combustion Chamber Deposit Measurement Techniques
SAE Technical Paper Series, 1994<div class="htmlview paragraph">Combustion chamber deposits (CCDs) have been quantified with a variety of methods in the past. Historically, the primary means of quantifying fuel related deposits involved either a visual rating, deposit weight, or an audible method.

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.

Tank Pressure from Combustion Chamber
Journal of the American Rocket Society, 1948T^HE simplest form of liquid-fuel jet engine for high-speed short-range missiles is the so-called one-shot system, in which the fuel and propellant are contained in tanks capable of standing the combustion-chamber pressure, and are forced into the combustion chamber by the pressure on an inert gas.
