Introduction to Computational Fluid Dynamics

Fluid dynamics controls everything from the aerodynamics of vehicles to the cooling of electronic components, but analyzing these complex flows requires powerful computational methods. This course provides a clear, structured introduction to Computational Fluid Dynamics (CFD), helping you transition from basic physics to numerical simulation. You will gain a solid understanding of how fluid behavior is translated into mathematical models and solved using modern computing techniques. By reading through this comprehensive guide, you will develop the theoretical foundation and practical intuition needed to set up, analyze, and interpret fluid flow simulations. You will start with the core governing equations, explore discretization methods, and learn how to evaluate simulation accuracy and stability. What you will learn: - Understand the physical principles behind the Navier-Stokes and Euler equations - Master the fundamentals of finite difference and finite volume discretization methods - Learn how to set up boundary conditions and grid generation strategies for stable simulations - Apply numerical algorithms to solve heat conduction and fluid flow equations - Analyze simulation convergence, stability, and potential sources of numerical error - Explore modern CFD practices, including turbulence modeling basics and verification workflows This course begins with essential terminology, governing equations, and foundational physics before guiding you through discretization techniques, grid generation, and solver algorithms. You will finish with a clear understanding of how to structure and verify a CFD analysis. This course is designed for engineering students, researchers, and professionals new to fluid simulations. No prior experience with CFD software is required, though a basic background in calculus and general physics will help you get the most out of the material.
