As the largest institution of research and education in Upper Austria, the Johannes Kepler University Linz has over 20,000 enrolled students and 3,000 employees. The JKU's four faculties offer over 60 academic degree programs. We announce an immediate opening for a
PhD student position (f/m)
at the Institute of Computational Mathematics
for a full time, three years at the LIT project:
Numerical simulation of incompressible non-Newtonian flows modeled by power-law Navier-Stokes systems.
The project concerns the development of novel and efficient space-time finite element methods for non-Newtonian fluid flow models, i.e., models where the stresses have nonlinear dependence on the shear rate. The discretization of these models is of great importance since they are met in many industrial areas, e.g., chemical engineering, lubrication and biofluid mechanics. Several finite element methods combined with implicit Runge-Kutta schemes (FEM-RK) have been presented over the past years for solving these types of problems. This project will study the current FEM-RK schemes and will further investigate the development of space-time finite element methods, which help in discretizing the problem in space and in time simultaneously. In this project the fully numerical scheme will be entirely developed by following finite element discretization concept. In the main goals of this project is the construction of fast and efficient non-linear solvers for solving the non-linear system arising after the finite element space-time discretization. The working plan includes both the materialization of the algorithms (scientific programming) and the analysis of the schemes. For the materialization of the algorithms known FEM libraries will be used, e.g., Deal.II. The applicant will work with Dr I. Toulopoulos in the frame of the associated JKU- LIT-project ‘Numerical simulation of incompressible non-Newtonian flows modeled by power-law Navier-Stokes systems.
The working language is English. The candidates should have (or expect to achieve) a master (or equivalent) degree in computational Mathematics, Scientific computing, Engineering or Physics. The candidates must have a background in computational linear algebra, numerical methods, fluid dynamics, programming skills in FEM methods.
