Section outline

  • An overview of the Finite Difference Method (FDM), one, if not the first, numerical method used in CFD.

    • Finite Difference File

      This document reports the Fundamentals of the Finite Difference method (FD) for Computational Fluid Dynamics (CFD) and Numerical Heat Transfer (NHT). In particular, after a general overview of the method and the presentation of the most frequent FD approximations for first and second-order derivatives, it illustrates some different techniques - Taylor series, polynomial interpolation and difference operators - which can be used to derive different schemes for the Finite Difference Equations (FDE) representative of their corresponding Partial Differential Equations (PDE).
