In order to understand the blood kinship 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 possibility and the validity of self-similarity for conservative properties. Validation of such concepts is achieved by comparison model predictions with both CFD gas jet simulat ions 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. All rights reserved.

Introduction The evolution of diesel engines in the last decades has been driven by the blotto befoulment legislation. In order to ful?ll the regulated limits, a detailed story of fuelair mixing and burning proc esses has been necessary. such a research t! ask has made it possible to optimise engine performance as well as to pass up pollutant emissions. apprehension of diesel sprays is essential in this optimization process. delinquent to the engine working principle, fuel and air meet interior the combustion chamber thanks to the spray momentum, which controls both fuel swarm penetration inside the combustion chamber and the concurrent mixing...If you call for to get a full essay, order it on our website: BestEssayCheap.com
