Computational fluid dynamics (CFD) is a powerful tool used by engineers and scientists to simulate and analyze fluid flow in complex systems. Synonyms for CFD include numerical fluid dynamics, computational hydraulics, and computational fluid mechanics. These terms describe mathematical methods used to solve equations that describe the motion of fluids in various systems. CFD has applications in fields such as aerospace, automotive, and marine engineering, as well as in the design of buildings, heating and cooling systems, and medical devices. Regardless of the terminology used, CFD remains an important tool for understanding fluid dynamics and optimizing the performance of various systems.
