Computational Fluid Mechanics II

Recommended Prerequisites

General Hydraulics I, General Hydraulics II, Numerical Methods, Hydrodynamics, Variable Flows and Computational Fluid Mechanics I.

For candidates who do not have deeply enough knowledge in these matters, it is recommended the frequency of these disciplines, with the contents offered in the doctoral program itself, possibly in a zero year.

Teaching Methods

Detailed theoretical exposition of the contents, followed by demonstration and applications using computer applications and, where possible and appropriate, comparisons with laboratory experiments.

Learning Outcomes

This course aims to provide a solid background for the student to be able to apply CFD methods as a tool for Civil Engineering applications. It also gives an understanding of the underlying methods such that the student will be able to interpret and write its own CFD codes. Accordingly, the following objectives are highlighted:
i)    to deepen the theoretical knowledge, whose foundations were acquired in previous disciplines,
ii)    touch on deep theoretical concepts, with a view to analyze turbulent flows, including computer applications in this area;
iii)    develop capacities of pure and applied research, and
iv)    develop ability to use modern engineering techniques and tools.

Work Placement(s)

No
