Ice sheets melt in contact with warm ocean water, which contributes to rising sea levels. The input of cold and fresh glacier water into the ocean also modifies ocean currents. The nonlinear feedback mechanisms in ice-ocean interaction are important to understand for reliable predictions of responses to climate change, but are also difficult to model. Simulations of the physical processes are sensitive to numerical approximation and discretisation techniques, are often subject to instabilities and set high demands on computing power.
This project aims to use and further develop modern methods from computational fluid dynamics for modeling of ice in contact with the ocean. The postdoctoral researcher will explore how level set and phase field method can be used to represent the ice/ocean boundary, as well as tools for turbulence modeling and non-Newtonian flow if of interest. Modern approaches and large-scale parallel simulations will be utilized.
The project is a collaboration between the department of Mathematics at Stockholm University and FLOW, KTH, in the Department of Engineering Mechanics. FLOW is a continuation of the Linné FLOW Centre at KTH started in January 2007 and is one of 20 original centres of excellence set up by the Swedish Research Council (VR), as the result of a highly competitive process with international evaluation. The role of FLOW is to bring together and coordinate the fundamental fluid dynamics research performed by the partners. The position is funded by SeRC (Swedish e-Science Research Centre), an environment within the strategic research area (SRA) of e-Science by the Swedish government Strategic Research Area Initiative. The mission statement of SeRC is to develop state-of-the-art e-Science tools and provide e-infrastructure support to existing and emerging e-Science communities to achieve scientific breakthroughs in Sweden.
