Computational Fluid Dynamics (CFD) is essential in aerospace engineering for simulating and analyzing fluid flow around aircraft and spacecraft. At its core, CFD relies on the numerical solution of the Navier-Stokes equations, which describe fluid motion, using discretization methods such as Finite Volume or Finite Element methods. Key aspects include generating high-quality meshes to accurately capture flow features, applying appropriate boundary conditions, and selecting suitable turbulence models to handle complex flow behaviors. CFD aids in optimizing aerodynamic performance, analyzing propulsion systems, and managing thermal conditions, ultimately enhancing design efficiency and performance in aerospace applications.
