Ph.D./Postdoc position
We are still seeking a candidate for an PHD/Postdoc position on "OpenFOAM 
modelling of crystal growth, sedimentation and visco-plasticity of the 
packed bed during solidification of alloys" 
Topic of Research 
During solidification of some alloys equiaxed grains form, grow and move. 
Small grains are carried with the melt flow, while with further growth 
grains often sink down and sediment. At a certain dense packing, they form 
a coherent network with intergranular/interdendritic liquid. Such a 
semi-solid slurry is known to have visco-plastic flow behavior. In 
addition, thermal contraction leads to a deformation of the solidifying 
part. In order to describe these phenomena it is suggested to combined 
three simulation approaches in the present project proposal: (i) a 
modeling approach which describes growth and sedimentation of crystals, 
(ii) a modeling approach which describes the mechanical behavior of the 
sedimented layer (visco-plasticity) and (iii) a modeling approach to 
describe the thermal contraction of the cast part. Recent developments 
describe the combined modelling of fluid/gas flow and deformation of 
solids (FSI: fluid-structure interaction), e.g. gas flow in exhaust pipes. 
The ideal candidate will investigate even more complicated configurations 
where the combination of flow with deformations in a solid is not done via 
a given surface (as in FSI) but through an a priory unknown volume, the 
two phase mushy zone. 
Education/Experience 
Requires a Bachelor/Masters/PhD degree in a relevant subject, e.g. 
metallurgy, engineering, physics, mathematics, computing;
Must have 2 or more years experience with CFD;
Experience with programming in OpenFOAM and/or C++ is essential;

desirable;
Applicants must be fluent in written English and have the ability to 
publish research papers at international level academic journals.
