Study of hybrid fuel injectors for aircraft engines

Abstract

This project is based on the fuel injectors initially; a multi-hole injector is designed and then the single-hole injector is attached and
converted to a hybrid injector, which is the hybrid combination of multi-hole and single-hole injector which could be controlled electrically.
All these processes are done with software. Solid works is used for designing and ANSYS is used for analysis of the 3D model. The massflow rate, pressure and velocity through the inlet and outlet is better when compared to other nozzles. This hybrid fuel injector hasthe added advantage of good atomization, providing better nozzle combustion. Then, the nozzle is used to operate a range of fuels,including JETA, kerosene, gasoline, diesel, and cryogenic fuel. Using the nozzle, each fuel exhibits various properties in terms of pressureand velocity. The designs are subjected to fluid flow simulation using ANSYS. Particularly, the liquid fuel are injected with very highpressure and velocity in order to atomize the fuel to form a homogeneous combustion. The present design is done for low viscous fue
