*********************************
Introduction to CFD, starting [...]from recalling the Navier-Stokes equation and the meaning of each term: unsteady term, convective term, viscous term. Why is CFD needed? Some reasons: when a system is difficult to study experimentally; to quickly test many scenarios; when it’s faster or easier than experiment; fluid simulations for entertainment. The basic ingredients of CFD: (i) the mathematical model; (ii) the discretization method; (iii) analysis of the numerical scheme; (iv) solving a resulting algebraic system of equations, and; (v) post-processing and visualization.

Finite volume formulas in two [...]dimensions— If FVM is applied on a Cartesian grid, we recover FD formulas! Finite volume equation for a general quadrilateral cell. The evaluation of fluxes is the crucial feature that differentiates the various schemes; examples: central scheme & cell-centered FVM / central scheme & cell-vertex FVM.

*********************************
Introduction to the Finite [...]Volume Method. The FVM is the most widely used method in CFD, and one of the reasons is that it is very general and flexible, and it allows the use of any unstructured mesh. It is characterized by using the integral formulation of the conservation laws, and the discretization is applied over infinitesimal control volumes. One of the most important features of the FVM is that it automatically results in a conservative discretization. A simple demonstration of this feature appears at the end of this video, where one domain is divided in three sub-domains, and the internal fluxes are seen to cancel out.

*********************************
Euler equations and the [...]shock-tube problem—The Riemann problem consists of a conservation law, and piecewise constant initial data with a single jump discontinuity. It has an analytical solution for the Euler equations, which is very useful to test numerical schemes. The Riemann problem itself appears as an integral part of the formulation of many CFD approaches, called “wave capturing methodsâ€. Classic example: “The shock-tube problemâ€: generates a one-dimensional unsteady flow consisting of a right-traveling shock and a left-traveling expansion wave.
