Traditional mathematical methods fail to handle most fluid dynamics issues because they require solving non-linear partial differential equations. The simulation of turbulent flows, on the other hand, is fraught with difficulties. The direct simulation of turbulence via the time-dependent Navier-Stokes equations dubbed Direct Numerical Simulation (DNS) still quite resources intensive. An ensemble averaging approach is used to decompose the flow variables into mean and fluctuation components before using Reynolds-Averaged Navier-Stokes equations (RANS). Applying the principles of RANS, this work has been carried out on three flow phenomena. For the first phase of the study, Transition over a flat plate has been considered and SST with transition followed by Transitional k-kl-ω has predicted the transition with utmost precision whereas the other models failed to capture the onset of transition. Transonic flow over an airfoil has been considered for the second phase of the study. In the second phase, where the shockwave-boundary layer interaction and the third phase of the study where the Shockwave phenomenon was studied, Menter’s SST and Realizable k-epsilon have predicted the Shock characteristics and Shock-Wave Boundary Layer Interaction Phenomenon with utmost accuracy. ICEM CFD has been used for structured grid generation and ANSYS Fluent has been used to carry out the Numerical Analysis. ANSYS CFD Post MATLAB and Microsoft Excel have been used for preliminary calculations and result interpretation.
