Abstract
This study presents a comprehensive numerical and experimental analysis of fluidic
thrust vectoring using shock vector control (SVC) in a two-dimensional convergentdivergent
(CD) nozzle. The research integrates computational fluid dynamics (CFD)
simulations and Schlieren imaging experiments to evaluate the effects of secondary flow
injection on thrust vectoring.
The study begins with the development and testing of a single-mirror Schlieren imaging
setup, which is utilized to visualize thermal plumes from candle and hand and later to
visualize supersonic flow structures inside and at the exit of the nozzle. The CD nozzle is
designed using the Method of Characteristics (MOC) and simulated in ANSYS Fluent to
investigate the effect of nozzle pressure ratio (NPR), secondary pressure ratio (SPR), and
secondary injection location on jet deflection. Experimental validation is conducted using
a 3D-printed nozzle tested in the test rig constructed locally.
