PhD scholarship in Dynamic Simulations of Fluid-Structure Interaction of Racing Sailboats DTU Mechanical Eng Share on Facebook Share on Twitter Share on Linkedin Thursday 15 Oct 20 Apply for this job Apply no later than 29 October 2020 Apply for the job at DTU Mechanical Eng by completing the following form. Apply online The Department of Mechanical Engineering at DTU is taking part in a research network on sports technology, together with other universities in Denmark. One of the projects is on numerical simulation of Racing Sailboats. The project is in cooperation with Aalborg University, University of Southern Denmark, Team Danmark and Danish Sailing Union. Sailboats are complex dynamic systems with interaction between fluid and mechanical forces and with large structural deformations. The goal of this project is to include all the necessary physics in a coupled dynamic numerical model to predict performance and motions of the boat. The resulting simulation model can be used to evaluate the effect of changes in trim, crew movement and equipment for different environmental conditions. These investigations can help sailors in their quest to win the race. Responsibilities and tasks The goal of the project is to develop the numerical simulation model, but other tasks are needed to support and validate the model. Since the project has more cooperation partners and stakeholders, coordination of the research activities is important. You will be responsible for: Development and validation of Computational Fluid Dynamics (CFD) model for aero and hydrodynamic forces on the boat Development and validation of a structural Finite Element Model (FEM) of sail, mast, hull structure and foils Coupling of structural and flow models in a combined dynamic numerical model Investigation of material properties of sails and if necessary, conduct testing of material properties of sail samples Coordination and execution of full-scale experiment to get validation data for the numerical model. This include finding relevant equipment suppliers and partners. Coordinate cooperation with external partners and stakeholders Execute simulation studies with the model to produce relevant knowledge for sailors and coaches at the danish national sailing team Publish scientific articles on the models and findings during the research The focus of the project is on racing sailboat, but the concept of dynamic simulation of sails and boat motions are relevant for the shipping industry as well. There is a strong push from industry and society to reduce carbon emission in the shipping industry. One of the technologies to reduce emissions is to use wind as a supplementary propulsion of the ships. Accurate modelling of the sails and wings for wind propulsion will be essential to speed up the development of new solutions for the industry. Qualifications Candidates should have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree. You should have experience with: Computational Fluid Dynamics (CFD) Finite Element Modelling (FEM) Simulation of Aerodynamic forces on sails, wind turbine blades or similar Simulation of Hydrodynamic forces on boats including free surfaces Documented experience with STAR-CCM Furthermore, organisational skills and experience with project management is an advantage.
