A CFD ANALYSIS OF LIQUID PROPELLANT INJECTOR FOR PERFORMANCE ENHANCEMENT OF SMALL THRUSTER
초록
CFD analysis of the fuel injection pattern and the flow field surrounding the liquid propellant injector of a small thruster is performed. A good agreement is shown with PIV test data for the initial configuration. Analysis on various injector shapes is performed to observe the effect of injector shape on the trajectories of liquid droplet. A various shapes of injector is investigated to enhance spray pattern of the small injector.
