In order to understand the consanguinity between fuelair mixing and spray penetration, a one-dimensional spray model is developed, which is capable of predicting the spray carriage under transient conditions. The main assumptions of the model are the mixing-controlled meditation and the validity of self-similarity for conservative properties. Validation of such concepts is achieved by par model predictions with both CFD gas jet simulations and experimental diesel spray measurements. Results show that a reasonable estimation of the spray evolution can be obtained for both non-vaporising and vaporising conditions. Ã" 2008 Elsevier Ltd.

Introduction The evolution of diesel engines in the last decades has been driven by the pie-eyed befoulment legislation. In order to ful?ll the regulated limits, a slender story of fuelair mixing and burning processes has been necessary. such(prenominal) a research task has made it possible to perfect engine performance as well as to get down pollutant emissions. apprehension of diesel sprays is essential in this optimization process. collect to the engine working principle, fuel and air meet inner the combustion chamber thanks to the spray momentum, whic h controls both fuel swarm penetration insi! de the combustion chamber and the synchronic mixing...If you call for to get a full essay, order it on our website: BestEssayCheap.com
