In order to understand the kind between fuelair mixing and spray penetration, a one-dimensional spray model is developed, which is capable of predicting the spray behaviour under transient conditions. The main assumptions of the model are the mixing-controlled venture and the validity of self-similarity for conservative properties. Validation of such concepts is achieved by equation model predictions with both CFD gas jet simulations and experime ntal 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 cockeyed befoulment legislation. In order to ful?ll the regulated limits, a little story of fuelair mixing and burning processes has been necessary. much(prenominal) a research task has made it possible to perfect engine performance as well as to frown pollutant emissions. apprehension of diesel sprays is essential in this optimization process. receivable to the engine working principle, fuel and air meet interior the combustion chamber thanks to the spray momentum, which controls both fuel swar m penetration inside the combustion chamber ! and the coinciding mixing...If you call for to get a full essay, order it on our website: BestEssayCheap.com
