Note:
SAMs 1.1.1 and 1.1.3; This NSF career work plan leverages the PI's expertise in the area of Direct Numerical Simulation (DNS), graphics processing unit (GPU) programming, thermal-fluids and scientific visualization to analyze the phenomenon of boundary layer separation in high-Reynolds number flows and its implication in passive scalar phenomena. The research effort consists of three main tasks. The first task involves performing DNS of spatially-developing turbulent boundary layers subject to the effects of streamwise and wall-curvature driven pressure gradient on flow separation with passive scalar transport. The second task aims at better understanding of the momentum/scalar transport phenomena in the separation process by means of low/high order statistics analysis. An important component of this task will be the identification of coherent structures by using the cutting-edge Lagrangian approach. The third task will involve a unique data-driven modeling of sub-grid scale (SGS) in Large Eddy Simulation (LES) of the complex geometries in Task 1, particularly focusing on the uncharted area of passive scalar SGS models under flow separation. To our knowledge, the proposed transformative DNS study at "experimental" Reynolds numbers will be carried out for the first time, shedding light on passive scalar under flow detachment; while the educational approach is designed in harmony with the research aspect.
