The design, improvement, and operation of engineering devices and processes involving fluid dynamics necessitate a profound understanding of fluid flow, combustion, and heat transfer. To develop new technologies, analytical and evaluation techniques are essential. In this context, Computational Fluid Dynamics (CFD) has become a prevalent and indispensable practice, being utilised in various applications. CFD enables the modelling and design of devices and processes, allowing for accurate predictions of detailed aerodynamic and performance parameters. As a result, it has become an invaluable research and development tool.

Recent advancements in Large Eddy Simulation (LES) techniques within CFD, coupled with the availability of high-performance computing (HPC) resources, have significantly enhanced the accuracy and realism of CFD calculations. Consequently, simulations have proven to be highly useful for the improvement of various processes. Notably, CFD modelling of combustion has opened doors to analysing complex devices such as gas turbines, internal combustion engines, and safety-related processes. Recently, hydrogen has emerged as an intriguing topic due to its potential as a future fuel, given its capacity to generate power without producing CO₂.

This discussion focuses on the current practices of Computational Fluid Dynamics techniques and modelling options. Furthermore, it explores how these techniques can be applied to tackle hydrogen-related challenges. The lecture presents and describes CFD combustion modelling applications in flames, internal combustion engines, and explosion scenarios, providing insights into the current state of advanced CFD applications in combustion research.
