AFFILIATED RESEARCHERS

Research Interests

Michal Beneš focuses on mathematical modelling and numerical simulation of nonlinear problems described by non-linear partial differential equations with the application in physics, environment protection and computer science. In particular, he is interested in models of coupled compositional free and porous media flow and transport and in multiphase porous media flow with phase transitions related to soil freezing and thawing.

Research Interests

The main topic of Jakub Klinkovský’s research are numerical methods in computational fluid dynamics and their implementation and optimization for modern parallel architectures, especially GPU. This includes discretization methods for partial differential equations as well as methods for the solution of the discrete problems, often in the form of sparse linear systems. In particular, one application of his research is the solution of two-phase compositional flow in porous media using the mixed-hybrid finite element method on GPUs.

Research Interest

Ondřej Pártl develops mathematical and numerical models for non-isothermal compositional compressible gas flow in a porous medium
and in the coupled atmospheric boundary layer above its surface with the application to the description of evaporation of NAPL from soil and hydration of a zeolite bed.

RESEARCH INTERESTS

Andrew Trautz investigates land-atmospheric interactions with respect to bare soil-water evaporation which presently is still poorly characterized and understood. His research involves both physical experimentation and numerical modeling. The experimental work is performed in laboratory scale tanks interfaced to a climate controlled wind tunnel. The precision data generated is in turn used in numerical models focused on coupling multiphase flow in porous media and free-fluid domains under varying atmospheric conditions. Current research involves the applicability of using heat-pulse sensor technology to determine evaporation rates in situ.

RESEARCH INTERESTS

Radek Fučík focuses on analytical and numerical solution of multi-phase compositional flow models in porous media, a posteriori error estimation in the finite element method, and development and implementation of the LBM for modeling of fluid flow and fluid-structure interaction applications on GPU.

RESEARCH INTERESTS

My research group investigates subsurface fluid flow, solute transport, and chemical reactions in soils, aquifers, and deep geological reservoirs. On the one hand, we work on theoretical, numerical, and computational problems ranging from the scaling theory, inverse methods, to high performance computing. On the other hand, we apply the techniques we develop to laboratory and field-scale problems to improve subsurface characterization and the understanding of a variety of fluid flow and transport phenomena (e.g., waste disposal, CO₂ storage, surface water groundwater interaction, and aquifer recharge).  Recently, to study bedrock hydrology in headwater regions, we have drilled, instrumented, and conducted well testing campaigns in fractured bedrock of the Laramie Range and mountain front areas in southeastern Wyoming. We further explore issues at the water/energy nexus to improve the safety, effectiveness, and economics of energy and water uses.
