    Computational Fluid Dynamics: Turbulence Modeling and Applications

    Turbulence/transition modeling is a primary source of uncertainty in computational fluid dynamics, and this problem remains unsolved despite over one hundred years of scientific research. The talk will focus on an overview of author's ongoing research in transition/turbulence modeling and applications. The key modeling topics that will be discussed are: identification of transition onset marker for bypass transition; modeling subgrid scale energy transfer using algebraic models; and potential of machine learning for turbulence modeling. The key application topic will focus on role of turbulence on: growth of vortical structures for ship flows; heat transfer; structural deformation for shock boundary layer interaction; growth of rotor wake; and propagation of acoustic waves. Some open question in transition/turbulence will also be emphasized.
