Computational Fluid Dynamics for Beginners

Understanding how fluids behave and interact with surfaces is critical in modern engineering, yet the underlying mathematics can feel overwhelming. This course breaks down the complex equations governing fluid flow into intuitive, manageable concepts that you can translate into working code. You will transition from understanding basic physical principles to confidently setting up and solving numerical simulations. By reading through this structured material, you will build a solid foundation in the mathematical models and computational techniques used to solve real-world fluid flow problems. You will learn how to translate physical phenomena into systems of equations and solve them using modern programming practices, including clean code structure and basic testing. What you'll learn: - Understand the governing equations of fluid flow, including the Navier-Stokes equations - Apply discretization methods such as Finite Difference and Finite Volume techniques - Configure numerical schemes to solve diffusion, convection, and conduction problems - Implement pressure-velocity coupling algorithms for incompressible flows - Analyze simulation stability, convergence criteria, and grid independence - Practice writing clean, modern Python code using type hints to build custom solvers We begin with essential terminology, governing physical laws, and foundational mathematical definitions. From there, you will progress step-by-step through discretization strategies, boundary conditions, and solver algorithms, complete with clear code snippets and conceptual exercises to reinforce your learning. This text-only course is designed for engineering students, software developers, and researchers who are new to numerical simulations. No prior experience with fluid dynamics software is required, though a basic understanding of calculus and introductory programming is helpful.
