Postdoc in Extensions to a Fast Nonlinear Coastal Wave Evolution Tool

jobbeskrivelse:
A one-year post-doc scholarship is available at Department of Mechanical Engineering at DTU, Technical University of Denmark, in the field of fast tools for predicting highly nonlinear waves in coastal regions. The department has well-established research programs in Coastal and Maritime Engineering, as well as Mathematical and Numerical Modeling of Ocean Waves and their interaction with Fixed and Floating Structures. This project is funded by the Danish Innovation Fund as part of the DeRisk project with the goal of improving the accuracy of the Ultimate Limit State (ULS) design loads on offshore wind turbines. The anticipated starting date is between July 1st and August 1st 2015. Responsibilities and tasks Cost reduction within offshore wind energy is vital for achieving the 2020 goal of 50% wind share of the Danish electricity supply. The DeRisk project is a collaboration between 8 partners and aims to provide new design methods with reduced risk and uncertainty for extreme wave loads (the ULS, or Ultimate Limit State) which are often design-giving for the support structure. DeRisk examines the design chain from met-ocean data to structural response. Joint probability methods are developed for analysis of met-ocean data. Wave transformation over depth is computed with ground-breaking fully nonlinear, GPU-accelerated (Graphical Processor Unit) wave models. Specialised tools for high-frequency ringing-type and breaking wave loads are developed and validated against high-quality experiments. This post-doc will be responsible for extending an existing fully nonlinear, GPU accelerated, wave model to allow for arbitrarily complex far-field boundary conditions in order to introduce 3D directional waves based either on theoretical descriptions or the motions of wave-paddles in an experimental facility. The extension will be made in collaboration with DTU Compute and DTU Wind Energy. A model for the dissipative effects of wave breaking will also be implemented. The implementation will be validated by comparison with a series of experiments in the wave tank, and kinematics data will be made available to the other project partners. Qualifications Candidates should have a PhD degree in Mechanical/Ocean Engineering or a similar scientific field. Strong skills are required in: scientific computing; fluid mechanics; applied mathematics; and programming in C/C++, Fortran, CUDA and Matlab; as well as a keen interest in nonlinear wave dynamics, wave-structure interaction and the associated physical processes. Documented knowledge and experience within hydrodynamics, linear and nonlinear wave theories and numerical solution of free-surface flow problems will be considered as an advantage. We offer We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world. Salary and terms of employment The appointment will be based on the collective agreement with the Confederation of Professional Associations. The allowance will be agreed with the relevant union. The period of employment is one year. Further information Further information may be obtained from Associate professor Harry Bingham, tel.: +45 4525 1972.
