1. Goals |
This course will deal with the methods and concepts of the numerical analysis of fluid flow governed by nonlinear systems of partial differential equations. We will study the basic discretization method and the relevant stability analysis, and extend them to the Euler and Navier-Stokes equations. Within the framework of the finite volume method, the numerical techniques to deal with nonlinear convective fluxes and time integration term will be covered. On top of it, the 1-D and 2-D numerical codes are programed, and applied to various test flow problems to examine the physical/numerical aspects of computational modeling. |
