MEAM Seminar: “The Simulation and Modeling of Turbulent Flows”
October 29 at 10:30 AM - 12:00 PM
Our group at the University of Minnesota focuses on fundamental advances in numerical algorithms, and understanding of flow physics that allow the prediction of engineering turbulent flows. This presentation will discuss key aspects of such simulation alongside illustrative examples. We will discuss a recently developed unstructured overset grid methodology and its application to particle-resolved DNS of several thousands of particles in turbulent flow. We will discuss global stability and adjoint analyses for three-dimensional complex baseflows, and illustrate its application to jets in crossflow. Finally we will present an integral analysis for axisymmetric boundary boundary layers in the presence of pressure gradients, and illustrate its application to interpret LES results.
