Biofuel usage has good environmental and economic benefits but at the same time it has weak performance and fuel efficient when compared to usage jet fuel in aircraft similarly release of sulphur particles will end solar radiation. In additionally to these barriers, flame speed of biofuel is very low compared to jet fuel flame speed so a new task is arrived here that is flame stabilization in combustion chambers while using blended biofuel with jet fuel. Hence, we are analysing aircraft turbofan engine combustion chambers both by theoretical and analytical manner about its working when using blended biofuel. Using NASA CEA online software, the combustor data are gathered and are compared with analysis of designed combustor in ANSYS analysis software. The flame analysis is more important when using the blended biofuel in different ratio.

SummaryMixing systems have many applications in gas turbines and aircraft jet propulsion, e.g. mixing zones in combustion chambers, ejectors for jet lift thrust augmentors and supersonic propulsion systems. A further application similar to that of combustion chamber mixing is that of mixing the cold and hot exhausts of a bypass jet engine. These are both characterised by mixing at constant static pressure and approximately constant total pressure as opposed to the more general case of unequal pressures in ejector systems (Fig. 1).The exhaust mixing process as used in Rolls-Royce bypass jet engines, e.g. Spey and Conway, enables the potential of the bypass principle, in terms of minimum weight and fuel consumption, to be exploited by a simple practical device.This is achieved by mixing the two streams in a common duct of fairly short dimensions with a corrugated metal interface on the inlet side. The consideration of these practical systems forms the main topic of this paper.

Good Agreement

A mathematical model for predicting spray–swirl interaction in a direct injection diesel engine combustion chamber is developed using centre-line velocity vector/continuum approach. The model has three-dimensional features in fuel spray motion. The present model responds to the various air swirl, fuel injection and cylinder charge conditions. The predicted results are compared with the analytical and experimental data available from various sources in the two-dimensional case. Very good agreement is achieved over a wide range of data. The three-dimensional predictions are directly possible without any alteration in the computation scheme.
