Student thesis: Master's Thesis


In micro turbojet engine the volume of combustor is smaller and the spindle speed is higher than large scale jet engine The fuel atomization is difficult in such a tiny space However the rotating fuel atomizer has successful experience in jet engine The development and design of small scale rotating fuel atomizer is a way to provide good spray quality for micro turbojet engine In this study fuel slinger was completely investigated with different rotating speed fuel flow rate orifice diameter and test liquid The experimental test were conducted by quantitative measurements The spray distribution and drop size measured by the EPCS (Ensemble Particle Concentration and Size) systems From the analysis of nondimensional parameter the SMD correlated factor between JP-8 and water is 0 57 The predicted SMD equation of JP-8 can be a reference for slinger design and future study
