Objectives
It is intended that the students acquire: the fundamentals of numerical methods for the solution of Navier-Stokes/Reynolds equations, the perception of how the commercial computer codes for computational fluid dynamics work, realize their potential and limitations; the computational practice that will allows to solve concrete problems of Fluid Mechanics in any field of engineering, particularly in mechanical engineering; and the ability to evaluate the solutions.
Prerequisites
It is supposed a strong domain of subjects learned in the courses: Numerical Analysis, Introduction to Computers and Programming, Fluid Dynamics I and II and Heat Transfer.
