Hierarchical Wavelet-based Modeling of Turbulent Flows

status: ongoing

Since the inception of Computational Fluid Dynamics, turbulence modeling and numerical methods evolved as two separate fields of research with the perception that once a turbulence model is developed, any suitable computational approach can be used for the numerical simulations of the model. Our group pursues a radically different philosophy in its belief that in order to substantially increase the computational efficiency of turbulent flow simulations and improve the accuracy of predictions of flow characteristics, numerical methods, mesh generation and physics-based modeling need to be tightly integrated to ensure better capturing of the flow physics on a near optimal adaptive anisotropic computational grid, ultimately leading to substantial reduction in the computational cost, while resolving dynamically dominant flow structures.
