Abstract. Microbial activity and chemical reactions in porous media depend on the local conditions at pore scale can involve complex feedback with fluid flow mass transport. We present a modeling framework that quantitatively accounts for interactions between bio(geo)chemical physical processes integrate genome-scale microbial metabolic information into dynamically changing, spatially explicit ...

We present simulations and analysis of the heating of warm dense matter (WDM) foils by ion beams with energy less than 1MeV per nucleon to target temperatures of order 1 eV. Simulations were carried out using the multi-physics radiation hydrodynamics code HYDRA and comparisons are made to an analytical model and the code DPC. We simulate possible targets to be used in a proposed experiment at L...

Buoyancy-induced (Rayleigh-Bénard) convection of a fluid between two horizontal plates is a central paradigm for studying the transition to complex spatiotemporal dynamics in sustained nonequilibrium systems. To improve the analysis of experimental data and the quantitative comparison of theory with experiment, we have developed a three-dimensional finite-difference code that can integrate the ...

The main objective of this work is the development a Computational Fluid Dynamics model coupled with structural code for simulation and optimization fishing gears. As nets are highly deformable structures under influence incident water, use merely empirical correlations hydrodynamic forces, such as those used in many codes, does not provide precise predictions their behaviour. coupling between ...

This paper describes an approach to predict the acoustic nearand farfields with minimal computational requirements. The near field flow time dependent pressure history in the flow is predicted from computational fluid dynamics either using readily available finite difference codes or using in house finite element research code based on Gradient Adaptive Transfinite Elements. This pressure histo...

in our present research, we focus on the modeling of airflow related to natural disasters, such assand accumulation, with urban form studies. the objective is to find which urban form can promote sand passing andreduce as much as possible stagnation of sand in the building area (streets, alleys, etc.). the urban form design will bediscussed through the simulation of airflow by using computation...

a novel computational fluid dynamics and molecular kinetic theory (cfd-mk) method was developed to simulate the impingement of a nanodroplet onto a solid surface. a numerical solution of the navier–stokes equation using a volume-of-fluid (vof) technique was used to model nanodroplet deformation. dynamic contact angle during droplet impact was obtained by molecular kinetic theory. this dynamic c...

Building design and operation often requires real-time or faster-than-real-time simulations for detailed information on air distributions. By solving the Navier-Stokes equations and transportation equations for energy and species, Fast Fluid Dynamics (FFD) model can provide detailed information as a Computational Fluid Dynamics (CFD) model. Compared to the CFD, the FFD is 50 times faster with s...
