¿Qué es un CFD? 3 junio 2010Posted by pbdfire in simulacion de incendios.
Continuamos con nuestra línea de definir y explicar términos relacionados con la simulación de incendios, y esta semana le toca el turno a los CFDs:
Según Wikipedia, un CFD (Computacional Fluid Dinmamycs), es lo siguiente:
“Computational fluid dynamics (CFD) is one of the branches of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the millions of calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. Even with high-speed supercomputers only approximate solutions can be achieved in many cases. Ongoing research, however, may yield software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial validation of such software is often performed using a wind tunnel with the final validation coming in flight test.”
