Numerical Analysis and Optimization of Anti-vortex Holes for Film Cooling, Ph.D. Dissertation Sharif University of Technology ; Mazaheri, Karim (Supervisor) ; Karimi, Mohsen (Co-Supervisor)
Abstract
The present thesis is devoted to deeply reconsider the anti-vortex film cooling method and its undiscovered features using numerical optimization and advanced turbulence models. In this regards, a modified turbulent heat-flux model was developed to enhance the predictions in complex flow fields with highly anisotropy and non-equilibrium flow/thermal features. Next, the model was introduced to ANSYS FLUENT 16.0 package to prepare a more accurate flow solver. Then, the solver was coupled with an in-house Differential-Evolution (DE) optimization algorithm to find the optimum configurations of anti-vortex holes for several flow and geometric conditions such as flat-plate, convex/concave surfaces...
