Abstract:
In the present study, the spraying behavior of diesel and kerosene fuel in a cylindrical fixed volume combustion chamber for a injector orifice has been investigated. In order to investigate the effect of injector geometry on fuel spray characteristics and atomization quality, different geometries have been used. For this purpose, the microscopic and macroscopic properties of the diesel and kerosene fuel spray for different geometries of orifice compression ignition injectors are modeled and investigated using AVL-Fire. Firstly, the liquid fuel flow inside the injector with cylindrical and converged conical nozzle holes have been modeled and then in the following diesel and kerosene fuels have been used in the grooved nozzle hole. Numerical results show that in this case, the kerosene spray has smaller penetration length and bigger cone angle than diesel fuel. Controlling the properties of the fuel spray is important to increase the combustion efficiency of the engine and also to reduce their pollution, and can be done by changing the geometry of the fuel injector nozzle.
