Course Description

The material in this course will encompass the modeling and simulation of turbulent flows, including direct numerical simulation (DNS), one-point closure models (Reynolds-averaged Navier-Stokes equation modeling, or RANS), probability density function modeling (PDF), and large-eddy simulation (LES).

Prerequisites

ME/AA 507 (or equivalent course), or permission of the instructor. It is advantageous, although not necessary, to have taken ME 543 (or equivalent course). Some basic knowledge of turbulent flows will be required; some acquaintance with stochastic processes will be helpful, although not required.
