Hands-on turbulence modeling with SGS, DES/IDDES, and real-world CFD case studies

What you'll learn
Derive the LES formulation from the Navier–Stokes equations using spatial filtering
Understand subgrid-scale (SGS) stresses and the physical role of SGS models
Implement and compare major SGS models: Smagorinsky, WALE, k-equation, dynamic, and hybrid RANS–LES (DES/IDDES)
Set up and run practical LES simulations for turbulent flow past a square cylinder
Analyze vortex shedding, wake dynamics, turbulence statistics, and mesh resolution requirements
Compare LES results with k-ω SST RANS to evaluate accuracy and computational cost
Apply guidelines for wall-resolved vs. wall-modeled LES in engineering problems

Requirements
Basic understanding of fluid mechanics and turbulence fundamentals
Familiarity with Reynolds-averaged Navier–Stokes (RANS) concepts
Basic knowledge of Linux/Unix environment and command-line usage
Prior exposure to OpenFOAM (case structure, running solvers, post-processing)
Understanding of numerical methods (finite volume method preferred)
Comfort with vector and tensor notation, calculus, and differential equations
(Optional) Basic scripting skills for post-processing and automation
