Wittgenstein's combustion chamber

Notes and Records of the Royal Society, 2009
Abstract Ludwig 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.

The Elbow Combustion Chamber

Journal of Fluids Engineering, 1946
Abstract A description is given of the “elbow” combustion chamber, developed for use in the gas-turbine power plant designed and built for the United States Navy by the Elliott Company. This type provides extremely high heat-release rates which is an essential characteristic for gas-turbine applications. The fuel-oil-burning system which

Combustion oscillations in industrial combustion chambers

Symposium (International) on Combustion, 1969
Combustion 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 ...

Feedback control of combustion oscillations in combustion chambers

Communications in Nonlinear Science and Numerical Simulation, 2010
Abstract 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 ...

The simulation of combustion flow of the supersonic combustion chamber

17th AIAA International Space Planes and Hypersonic Systems and Technologies Conference, 2011
The phenomenon of supersonic combustion chamber is very complex, full of shock wave system, expansion wave system. It is related to the supersonic, hypersonic flows in the shock/shock intersection, shock wave and boundary layer interaction, separated flow, fuel flow, as well as the complex structure of vortex structures.

Stability of the combustion process in elastic combustion chambers

Journal of Applied Mechanics and Technical Physics, 1968
High-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 ...

The Quiescent Combustion Chamber

Journal of Fluids Engineering, 1931
Abstract 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 ...

Combustion Chamber Modeling

2019
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.
