Project Description
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 velopment
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.
