INTRODUCTION
Understanding fluid behaviour is essential for designing efficient and innovative systems across various industries, including aerospace, automotive, energy, chemical processing, and biomedical. Computational Fluid Dynamics (CFD) enables engineers and researchers to simulate and analyse fluid flow, heat transfer, and other related phenomena using advanced numerical methods. This course provides an engaging and practical introduction to CFD, equipping you with the knowledge and skills to address complex fluid dynamics challenges.
CFD has transformed engineering by minimising the need for expensive physical testing and facilitating rapid design iterations. By simulating fluid flow in virtual environments, engineers can optimise product designs, predict system performance, and identify potential issues before manufacturing starts. This course demystifies the complexities of CFD and provides a step-by-step approach to help you confidently set up, run, and study simulations.
We begin by exploring the core principles of fluid dynamics and heat transfer, concentrating on the governing equations describing fluid behaviour. Participants will gain insight into how these equations are translated into computational models. As the course advances, you’ll learn best practices for geometry creation, mesh generation, solver selection, and post-processing of results.
Equally important is understanding how to interpret and validate simulation results against experimental or theoretical data. This course will guide you through validation techniques, ensuring that your simulations are accurate and reliable. You will also explore optimisation strategies to enhance design performance and identify the key parameters affecting system efficiency.
By the end of this course, you will have a solid foundation in CFD and the confidence to apply it to practical engineering challenges. Whether you are an engineer, researcher, or student looking to expand your analytical capabilities, this course provides the knowledge and tools to make CFD an essential part of your skill set.
