The history of Computational Fluid Dynamics (CFD) is intertwined with the development of computers and numerical methods. Its evolution can be traced through several key milestones:

• Early Developments (Pre-1960s): The foundation of CFD was laid in the early 20th century with the development of numerical methods for solving fluid dynamics equations. However, these methods were limited by the computational power available at the time.
• Emergence of CFD (1960s-1970s): The advent of digital computers in the 1960s enabled the practical application of numerical methods to fluid flow problems. Early CFD codes were developed for solving simple flow configurations.
• Advancements in Algorithms and Software (1980s-1990s): Significant progress was made in developing more efficient and accurate numerical algorithms, such as finite volume methods and turbulence models. Commercial CFD software packages like ANSYS Fluent and STAR-CD emerged during this period.
• Increased Computational Power (2000s-Present): The exponential growth in computing power has enabled CFD to tackle increasingly complex problems, such as simulating turbulent flows in complex geometries. High-performance computing (HPC) and parallel processing have become essential tools for CFD analysis.
• Integration with AI and Machine Learning (Present and Future): Current research focuses on integrating AI and machine learning techniques into CFD to improve model accuracy, accelerate simulations, and automate design optimization.

Key Figures in CFD History:

• Lewis Fry Richardson: Pioneered numerical weather prediction, laying the groundwork for CFD.
• Alexandre Chorin: Developed the vortex method for simulating incompressible flows.
• Brian Spalding: Made significant contributions to finite volume methods and turbulence modeling.

The future of CFD is bright, with ongoing advancements in algorithms, software, and computing power promising to further expand its capabilities and applications.
