-
A brief review of vectors and tensors, and in particular their features and properties most relevant in CFD.
-
An overview of the Finite Difference Method (FDM), one, if not the first, numerical method used in CFD.
-
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).
-
-
In this document, the Finite Volume Method (FVM) - one of the methods most commonly used in CFD - is described in some detail. Starting from the generic transport equation for Cartesian structured grids, the segregated and coupled methodologies for the solution of the flow and energy equations for such grids are then addressed. It follows with a description of the major features and properties of the method when applied to the transport equation for general, polyhedral-type, unstructured grids.
-
The Finite Volume method is presented for cell-centered grids. Cartesian and generally unstructured, polyhedral grids are considered. The main contents are:
- Generalities and the basic idea
- The computational grid
- Spatial discretization
- The steady case: surface and volume integrals, source term
- Interpolation techniques
- Final algebraic equation
- Boundary conditions
- Temporal integration
- Application to the generic transport equation
