Computational Fluid Dynamics and Heat Transfer for Beginners

Simulating how fluids move and how heat transfers is critical to modern engineering, from aerospace design to electronics cooling. This text-only course provides a clear, step-by-step introduction to computational fluid dynamics (CFD) and heat transfer analysis, breaking down complex mathematics into logical, practical concepts. You will transition from basic physical principles to writing clean, structured code that solves real-world engineering problems. You will begin by building a rock-solid foundation in governing equations, discretization techniques, and boundary conditions before moving on to practical implementation. To keep your skills modern, the course also introduces basic code structure, modular programming patterns, and verification methods to ensure your simulations are accurate and reliable. What you'll learn: - Understand the governing differential equations for fluid flow and heat transfer - Apply finite difference and finite volume methods to discretize physical domains - Solve steady and unsteady conduction problems using numerical approximation - Implement pressure-velocity coupling algorithms for incompressible flows - Write clean, modular code to simulate fluid behavior and thermal distribution - Verify simulation accuracy using basic grid convergence techniques This course starts with essential physical definitions and mathematical foundations, then guides you through the process of translating equations into running simulations. You will read comprehensive explanations, study structured code snippets, and work through analytical exercises that reinforce your understanding. This course is designed for engineering students, researchers, and self-taught developers who want to understand the inner workings of CFD. No prior background in computational simulation is required, though basic familiarity with calculus and introductory programming is helpful.
