The aim for the post-doc position is to develop a numerical model to predict the generation of bubble curtains for the required distribution and size of bubbles such that they can be used for effective noise mitigation during piling. Existing numerical models will be used to predict the generation of the bubble curtain and results will be compared with those of laboratory test or full scale measurements. In addition it is desirable to quantify the power consumption of the compressors and analyse the air flow rates and pressure drops along the length hoses
This post-doc position is part of the Joint Industry Project ‘Bubbles’ within the GROW joint research programme on offshore wind energy. Bubbles JIP will contribute to more efficient and effective designs of bubble curtains to reduce noise during offshore installation. This project researches the current practice of bubble curtain generation, sound propagation of piling noise through water and soil and the physical mechanism of noise attenuation by air bubbles. The project also includes the development of technology to measure the bubble size distribution and concentration over the water depth, also in relation to waves and current.
The tentative starting date is October 1, 2020 and the duration of the project is 1 year.
Department The Department of Hydraulic Engineering is mainly concerned with major surface waters such as rivers, estuaries and seas. The focus is on understanding, designing and implementing human interventions in the natural environment for the discharge of water, for protection against water, for transport over water and for buiding in water.
Within the department, the Offshore Engineering group conducts applied and fundamental research of value to the offshore engineering community. Alongside the research activities, the group is strongly involved in education within the Offshore and Dredging Engineering interfaculty curriculum. Both the research and education are carried out in close cooperation with the energy-oriented companies focused on the offshore developments. The research mission of the group is to provide mechanics-based tools and solutions to offshore engineering challenges. The focus of the research is placed on the integral modelling and design of offshore structures under various loads such as wind, waves, currents and ice. Currently on the frontline are the research projects associated with the deep water challenges, developments in the Arctic and expansion of the offshore wind sector.
Requirements The candidate should: hold a Ph.D. degree in fluid mechanics or related field;
have some background knowledge in the field of offshore engineering;
have experience with advanced numerical modelling and programming;
have strong analytical skills;
be eager to work at the intersection of several research domains.
have an excellent knowledge of the English language.
