Large Eddy Simulations Of A Cylindrical Film Cooling Hole

Large Eddy Simulations are used to explore the unsteady jet-in-crossflow interactions arising from discrete hole film cooling. The numerical grids are created using GridPro and exported into OpenFOAM for solution with specified initial and boundary conditions. A recycling-rescaling technique is used to generate an incoming turbulent boundary layer upstream of injection. The geometry and flow conditions are specified to match conditions of an experiment in open literature for robust validation of the numerical solution. The trajectory and spreading of the jet is discussed in terms of the insight provided by the results of the simulation.
