Aerodynamics of Combustion Chambers for Aeronautical Engines

1996
The aerodynamics of combustion chambers for aeronautical engines is studied by means of a compressible Navier-Stokes solver without chemical reactions. The three-dimensional (3-D) code is designed for the simulation of complex geometries by introducing non orthogonal curvilinear coordinates. The implicit solver, which is based on the scalar approximate

Computation of azimuthal combustion instabilities in an helicopter combustion chamber

14th AIAA/CEAS Aeroacoustics Conference (29th AIAA Aeroacoustics Conference), 2008
This work presents a detailed study of the first azimuthal mode of an annular helicopter combustor. First it is shown that the casing and geometrical details such as primary holes have to be accounted for to produce correctly the acoustics of the combustor. Then a methodology to compute azimuthal combustion instabilities is presented.

The impact of combustion chamber configuration on combustion and emissions of a single cylinder diesel engine fuelled with soybean methyl ester blends with diesel

, 2019
The multi-dimensional computational fluid dynamics (CFD) simulation involving in-cylinder flow and combustion have been done to study the effect of soybean methyl ester and piston bowl configuration on performance, combustion and pollutant emissions from

Onset of detonation in hydrogen-air mixtures due to shock wave reflection inside a combustion chamber

Acta Astronautica, 2018
Hydrogen fuel, as for now, is the most energy efficient and clean fuel for aviation engines. At present time RAM engines based on chemical burning of fuels and accelerating exhaust gases practically reached the top of their efficiency in terms of ...

Combustion Chamber Deposit Flaking

SAE Technical Paper Series, 2000
<div class="htmlview paragraph">There is increasing concern that small flakes of combustion chamber deposits (CCD) can break lose and get trapped between the exhaust valve and the seat resulting in difficulties in starting, rough running and increase in hydrocarbon emissions. In this paper we describe experimental observations which might explain

Internal combustion engine with a porous combustion chamber

MTZ worldwide, 2003
The 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.

A Modeling Theory of Combustion Chambers

Combustion Science and Technology, 1980
Abstract It becomes more difficult and expensive to design and test new combustors for large jet engines which require increasing mass flow rates and temperature and pressure levels. Therefore, it is important to study the scaling laws of combustor performance and to provide the modeling rules for practical use for the development and application of ...
