CV:
Bernard Meulenbroek is assistant professor in the Mathematical Physics section. He is interested
in the mathematical modelling of flow through porous media. In the previous years he has worked
with both academic and industrial partners on a number of applied problems such as (microbial)
enhanded oil recovery, CO2 sequestration and geothermal energy.
Modelling these problems often leads to a set of coupled partial differential equations (PDEs).
These PDEs are highly nonlinear as dictated by the physics of the underlying (applied) problem,
which leads to challenging mathematical problems. A further complication can be the presence of
so called "degenerate diffusion", which means that the PDEs become (almost) hyperbolic. Using
analytical and numerical methods the model equations are solved and the stability of the resulting
solution profiles is studied.
In an ongoing project he is working on the (prevention of) clogging of geothermal systems; this is
challenging from a modelling as well as a mathematical perspective. Temperature effects are now
expected to play a large role, which means that our terms in the PDEs (e.g. reaction rates) may
become highly nonlinear. In another project he will focus on the interface stability in twophase
flow in the case of degenerate diffusion.
