Abstract

Precision in CFD simulations proves difficult to attain because fluid dynamics combining with turbulence and boundary effects makes the system very complex. To solve existing challenges in CFD modeling mathematical methods function as essential enhancement tools that offer better numerical schemes together with turbulence models and data assimilation methods. This paper demonstrates how progressive mathematical models enhance CFD simulation precision through discussion of essential methodologies with supporting comparative research and practical applications.
