The accuracy of modern state-of-practice computational fluid dynamics approaches in predicting the cooling effectiveness of a perforated plate film-cooling arrangement is evaluated in ANSYS Fluent. A numerical investigation is performed using the Reynolds Averaged Navier Stokes equations and compared to NASA Glenn’s available Turbulent Heat Flux 4 experimental measurements collected as a part of the Transformational Tools and Technologies Project. A multiphysics approach to model heat conduction through the solid geometry is shown to offer significant improvements in wall temperature and film effectiveness prediction accuracy over the standard adiabatic wall approach. Additionally, localized gradient-based grid adaption is analyzed using the multiphysics modelling to determine the effectiveness of grid adaption in improving flow prediction accuracy. Finally, a Delayed-Detached Eddy Simulation using conjugate heat transfer is performed to demonstrate the improved velocity and temperature prediction accuracy over steady-state simulations, particularly in regions with large turbulent shear and boundary layers.
