Full Title
Optimal control of phase separation phenomena.Project Description
Controlling phase separation processes in material science allows to influence the quality, functionality or life time expectancy of materials. Utilizing a phase field approach coupled with relevant physical phenomena such as either the Navier-Stokes system or the Navier-Lame system the project work aims at deriving first and second order optimality characterizations for the associated optimal control problems and efficient numerical solution algorithms relying on adaptive discretization and Newton-type solvers. The derivation of optimality conditions is challenged by the nature of the free energy involved in the phase field model, and the solver design has to cope with potentially involved non-differentiabilities and the large scale of the discretized systems.Project Website at MATHEON
