MAS532 Numerical methods in hydrodynamics

Contents and structure

Numerical methods in Marine hydrodynamics gives an in-depth overview of applying advanced numerical methods in hydrodynamic analysis of flexible floating offshore structures. The course gives a comprehensive grounding, from first principles of dynamic stability, through to complex nonlinear fluid-structure interaction with flexible elastic structures. As a central course on the Master in Sustainable Energy Technology, the Marine structures is rooted within the UN’s 17 Sustainable Development Goals, covering advanced topics especially relevant for the demands of new offshore renewable energy technologies (SDG7), aiming to inspire new innovations (SDG9) which are capable of being produced responsibly (SDG12) and in consideration of the marine environment (SGD14) The following topics are covered:

• Review of ship stability
• Dynamic response - frequency domain and response amplitude operators
• Large-volume structures - 2D strip-theory and diffraction modelling
• Time-domain analysis - Cummins’ equation
• Numerical methods for flexible structures - hydro/aeroelasticity

Entry requirements

None.

Recommended previous knowledge

MAS116 Hydrodynamics, MAS220 Introduction to Fluid Dynamics, MAS224 Rigid body dynamics

Teaching methods

Traditional lectures, practice calculations, group project assignments.

Several short problem-based learning tasks, conducted in small groups and on topics relevant for the course.

Compulsory learning activities

In small groups, students are required to complete several short problem-based learning tasks, which form the basis of the portfolio examination.

One mid-way obligatory assessment of current portfolio. Submission must be accepted, before the portfolio may be submitted for final examination.

Assessment

Portfolio examination consisting of several short group reports based on the problem-based learning tasks, along and oral adjustment examination.

Grading scale is A-F, where F is fail.

Oral adjustment examination allowing for a maximum grade adjustment of up or down one grade.

A failed portfolio can only be retaken next time the course is taught.
