The study on jet mixing characteristics by varying the lip thickness has been done by the many researchers in low subsonic, high subsonic, and sonic Mach numbers (0–1.0). Additionally, researchers have performed supersonic primary jet surrounded by subsonic and sonic secondary jet. The jet mixing characteristics of a supersonic primary jet surrounded by a supersonic co-flowing jet with varying lip thickness have not been performed yet. The present study probes into this numerically. Numerical results were validated with existing experimental results in the open literature. Centerline pitot pressure is calculated using the Rayleigh pitot tube formula. Results show that increasing lip thickness enhances mixing and vice versa. The numerical shadowgraph shows the shock wave propagation and its interaction. Supersonic jet phenomenon such as supersonic core, Mach disk, oblique shock waves, shock crossover, expansion waves, subsonic flow pockets behind Mach disk, recirculation zone, near-field turbulence, subatmospheric region (wake), shear layer, characteristic decay region, fully developed region, and jet interaction was studied.
