A Study on Transient Combustion of Fuel Spray : On Diesel Combustion

摘要

In heat engines, i.e., boilers, gas turbines, diesel engines etc., the burning of the injected fuel spray is a very important problem. Since an intermittent injection is adopted especially in a diesel combustion, it is important to solve its transient combustion of spray in order to improve the performances of engines.　　In this paper, the calculatons of the combustion rate of fuel spray were carried out by assuming that the fuel spray was simply a gathering of a single droplet and each droplet was exposed to the thermal reactions in the presence of the oxygen. As the calculations，it was cleared out that the general behavior of the transient combustion in a diesel engine could be explained qualitatively by the methods of calculations　stated in this paper.
