A Mechanical Engineer specializing in Computational Fluid Dynamics (CFD) applies simulation techniques to analyze fluid flow, heat transfer, and related physical phenomena in engineering systems. They use CFD software to model aerodynamics, cooling systems, HVAC, and other applications to optimize designs before physical prototyping. This role requires a strong foundation in fluid mechanics, thermodynamics, and numerical methods, along with proficiency in simulation tools like ANSYS Fluent, OpenFOAM, or STAR-CCM+. Mechanical Engineers in CFD work in industries such as aerospace, automotive, energy, and manufacturing to enhance performance, efficiency, and safety of products and systems.
