Advanced fluid dynamics modeling for marine engineering applications

General details of the subject

Face-to-face degree course

Description and contextualization of the subject

The module concerns the applications of the fundamental equations governing the Fluid Mechanics of Newtonian fluids (Continuity, Navier Stokes and Energy Equations) to key issues of aerodynamics specific of marine engineering applications, such as the characterization of the boundary layer or the generation of lift and drag. It will be shown how these equations may be adapted and simplified to describe laminar flows, turbulence, and compressible flows. Appropriate solutions and techniques for each type of flow will be presented. The aim here is presenting correct simulation procedures of different types of flow for reliable CFD simulations in marine applications including ¿flow control devices¿ designed to maximize the efficiency of wind turbines.

The objectives are to provide students with the following benefits:

(1) Understanding the concept of fluid and the models of fluids

(2) Understanding and application of the basic physical flow equations

(3) Understanding the wind turbine rotor aerodynamics

(4) Ability to simulate the flow over different geometries with internal/external flows, including both laminar and turbulent regimes significant to marine engineering applications

(5) Ability to cooperate with the team members

Ordinary call: orientations and renunciation


The subject is assessed according to two methods:

1. Attendance and participation in the expositive classes: 30 - 70 %

2. Individual and/or collaborative tasks: 30 - 70 %

To decline to follow the continuous assesment methodology, the student must request it in writing to the lecturer responsible of the subject, within a period of not less than a week from the official date of the final exam established for the subject. The final exam can be sat in the ordinary call by those students that have declined to follow the continuous assessment.


In the case of a renunciation to the continuos assessment the student can sit a final exam that can contain the analysis of theoretical aspects and/or the resolution of practical cases with the same orientation and difficulty as the cases solved in class.

To pass the subject, a minimum global mark of 5 (pass) is needed.

Extraordinary call: orientations and renunciation


In the case of not having passed the subject in the ordinary call, the student can sit a final exam in the ordinary call. The exam can contain the analysis of theoretical aspects and/or the resoluction of practical cases with the same orientation and difficulty as the cases solved in class.

To pass the subject, a minimum global mark of 5 (pass) is needed.
