Generation and Analysis of Waves in Physical Models (2025)
Doctoral School of Engineering and Science at Aalborg University
Welcome to Generation and Analysis of Waves in Physical Models (2025)
Description:
The course deals with advanced methods and techniques in generation and analysis of waves in physical models. The course will cover analysis of long and short-crested waves, generation of linear and nonlinear regular waves, generation of oblique waves and associated laboratory difficulties, generation of long-crested and short crested irregular waves, wave reflections and associated laboratory difficulties, active absorption in flumes and basins, wave groups, bounded long waves and wave generator choice and design.
The course will be lectures followed by laboratory exercises to get hands on experience with the different methods
