For MARIN Academy we are looking for a student for the following MSc internship/assignment:
“Mastering breaking waves at the new MARIN facility”
A unique Multiphase Wave Lab (MWL) is being established by the Sloshing of Liquefied Natural Gas (SLING) research project to examine sloshing impacts in LNG tanks. SLING is a major public-private cooperation that has been created through the NWO ‘Perspective Programme’. The SLING consortium comprises the technology foundation NWO, four top Dutch universities, representatives from the LNG, shipping and shipbuilding industry, engineering companies and MARIN.
In the new Multiphase Wave Lab (MWL) in Marin, wave impacts to a rigid wall at different conditions are investigated. Waves are generated using a wave-focusing technique in a 13 m long, 600 mm wide flume tank with a piston type wavemaker and controlled water level and water temperature. The flume tank is placed in an autoclave in which the temperature, pressure and gas composition (which could be one or more of air, steam, nitrogen, helium and SF6) are precisely controlled.
Multi-Phase Wave Lab – a world first
The gas temperature is controlled from 15 °C to 180 °C and the pressure is controlled between 5 mbar vacuum and 10 bar gauge. Wave propagation and impact is observed with cameras placed at the outside of the autoclave.
Breaking waves observation
We are looking for a master student interested in doing his/her thesis at MARIN on the topic of generation of accurate and repeatable breaking waves using the flume tank of MWL. The work involves observation and analysis of the global flow of generated wave using slow speed cameras and digital image processing, quantification of variability, identification the sources of variability, and correction at the source. Theoretical and experimental approaches are required, and the student will be supervised through the following phases:
- Definition of the problem
- Studying the state of the art of wave generation and observation
- Elaboration of the solution for the generation of repeatable and accurate waves in a variety of conditions
- Implementation of the solution through experimental work and creation of signal correction files
- Evaluation of results
A first impression of the state of the art can be gotten here:
The internship is for the duration of 9 months. The start date of the internship period can be determined in consultation with the supervisors.
- Master student in Hydraulic Engineering, Marine Technology, Naval architecture or other related fields
- Interest in hydrodynamics
- Knowledge of programming in Matlab and/or Python
- Experience in digital image processing and fluid particle velocity measurement techniques is a plus
Department and supervisor
During the internship, you will be connected with the department T&M of MARIN. The supervisor for this internship, Vladimir Novakovic, is working as Project Manager at the T&M Department.
