Lecture
Turbulence: Modeling and Simulation
Description
This lecture covers the modeling of turbulence in fluid dynamics, focusing on Reynolds-Averaged Navier-Stokes (RANS) equations and turbulent viscosity models. It explains the Boussinesq hypothesis, different turbulence models like mixing length, Spalart-Allmaras, k-epsilon, and k-omega, and their implementation in numerical flow simulations. The lecture also delves into one and two-equation models, including the turbulent kinetic energy model and Reynolds-stress model, highlighting their strengths and limitations in various flow scenarios.
