Wittgenstein's combustion chamber
Notes and Records of the Royal Society, 2009Ludwig Wittgenstein, destined to be one of the most influential philosophers of the western world, entered Manchester University in 1908 as an aeronautical engineering research student. At Manchester he devised and patented a novel aero-engine that employed propeller-blade tip-jets.

Combustion is a chemical reaction that occurs between a fuel and an oxidizing agent that produces energy, usually in the form of heat and light. During combustion, oxygen is combined with different elements of the fuel, like carbon, hydrogen, sulfur, etc. and produces the respective oxides.

Feedback control of combustion oscillations in combustion chambers
Communications in Nonlinear Science and Numerical Simulation, 2010Abstract Model-based algorithms are generally employed in active control of combustion oscillations. Since practical combustion processes consist of complex thermal and acoustic couplings, their accurate models and parameters may not be obtained in advance economically, a model free controller is necessary for the control of thermoacoustic ...

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 ...

Optimizing an oscillation absorber in a combustion chamber
Journal of Applied Mechanics and Technical Physics, 1994The authors study the qualitative behavior of acoustic oscillations in a combustion chamber containing a dynamic absorber. A simple model is constructed that describes the forced one-dimensional oscillations. Target functions are proposed, and their behavior is examined in relation to the control parameters of the absorber.
