The Chair of Building Physics of ETH Zurich is performing multiscale research on the interaction of fluids with porous materials. In collaboration with the Laboratory of Multiscale Studies in Building Physics of Empa, we are recruiting a
PhD student on “Heat and moisture transport under partial freezing and frost damage in porous media though advanced modeling and experimental investigations”
We are looking for a highly skilled and motivated candidate that will investigate heat and moisture transport in porous materials under partial freezing. Frost damage in porous materials is of great interest in a wide range of fields, e.g. civil engineering, food engineering, geomorphology, and in particular for this project, for the retrofit of historical buildings. To this effect, a heat and moisture transport model for partial freezing will be coupled to a poro-mechanical damage model. Freezing-induced moisture transport towards the freezing zone and pore size-dependence of freezing temperature are included. Experiments are conducted using classical approaches combined with advanced imaging with X-ray and neutron at pore and macro-scale, to document the transport and damage processes. A damage assessment methodology for frost damage in retrofitted masonry will be developed.
The candidate should be a responsible and communicative scientist with a master degree in mechanical, civil or material engineering, physics, materials science, or similar field. Optimally, the candidate should have a strong background in heat and mass transport and/or in imaging of porous materials. A good background in computer programming with good knowledge of either Fortran or C++ is advantageous. The candidate should be proficient in English.
