dc.description.abstractThe objective of this work is to model under- and over-expanded turbulent compressible supersonic jets impinging on an axisymmetric jet deflector. The closure of the system of equations is achieved using a two-equation turbulence model with, an optional compressibility correction. A finite-volume discretization is carried out in spatial coordinates to compute inviscid and viscous flux vectors. A multistage Runge- Kutta time stepping scheme is used to obtain a steady state solution. The numerical algorithm is developed by taking into consideration structured grid arrangement. The numerical results are obtained for nozzle exit Mach number of 2.2 and 3.1, exit to ambient pressure ratio of 0.8 and 1.2, and at different distance from nozzle exit to the apex of the deflector. The numerical scheme is shown to be computationally fast, easy to program and efficient. The centre line pressure variation inside the jets differs in the presence of the jet deflector. The numerical results are compared with the available experimental data and are found to be in reasonably good agreement.en_US
