Abstract. Numerical investigations of fluid structure interaction between unsteady flow and vibrating liner in a combustion chamber are undertaken. The computational study consist of two approaches. Firstly, a partioned procedure consists of coupling the LES code AVBP for combustion modelling with the FEM code CaluliX for structural dynamic analysis. The CFD code CFX together with the FEM Ansys...

Homogeneous Charge Compression Ignition (HCCI) combustion is a pioneer method of combustion in which pre-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. HCCI engines can operate with most alternative fuels, especially, dimethyl ether (DME) which has been tested as a possible diesel fuel due to its simultaneously low NOx and PM emissions. In this paper a ...

With the rapid depleting of fossil fuels and its pollution intensive research is going on for the alternative fuels which produce low emissions and are should be renewable. Due to the production of sugar cane in our country is more (alcohol is a byproduct in the production of sugar), alcohol is considered as a preferable replacement for the diesel. However due to alcohol high latent heat of vap...

reactivity controlled compression ignition (rcci) is a novel combustion concept which uses port fuel injection (pfi) of a low reactivity fuel and direct injection (di) of a high reactivity fuel with optimum multiple injection to provide a stratified mixture inside the combustion chamber. piston bowl design has a considerable effect on engine’s pollutant emissions specially unburned hydrocarbons...

This paper illustrates the utility of developing compu­ ter models to predict and evaluate performance of com­ plex systems, in this case a dual combustion chamber incinerator of the type normally operated with starved air in the primary chamber, and equipped with a heat recov­ ery boiler. Once the model has been written, it can be used for construction of performance curves and examina­ tion o...
