Stimulated by a recent controversy regarding pressure drops predicted in giant aneurysm with proximal stenosis, the present study sought to assess variability prediction of pressures and flow wide variety research groups. In phase I, lumen geometry, rates, fluid properties were specified, leaving each group choose their solver, discretization, solution strategies. Variability was assessed having interpolate results onto standardized mesh centerline. For II, physical model geometry...
With the increased availability of computational resources, past decade has seen a rise in use fluid dynamics (CFD) for medical applications. There been an increase application CFD to attempt predict rupture intracranial aneurysms, however, while many hemodynamic parameters can be obtained from these computations, date, no consistent methodology prediction identified. One particular challenge is that factors contribute its accuracy; mesh resolution and spatial/temporal discretization alone...
The importance of Indoor Air Quality (IAQ) has been highlighted by the COVID-19 pandemic, particularly due to possibility long-distance airborne transmission. Consequently, assessment ventilation rates and estimation infection risk become a matter utmost importance. In this paper, naturally ventilated elementary school classroom is studied, where carbon dioxide (CO2) concentrations were measured during five months. Ventilation are calculated via fully-mixed box model for SARS-CoV-2 assessed....
The use of Computational Fluid Dynamics (CFD) to assist in air quality studies urban environments can provide accurate results for the dispersion pollutants. However, due computational resources needed, simulation domain sizes tend be limited. This study aims improve efficiency an emission and model implemented a CPU-based solver by migrating it CPU–GPU-based one. migration functions that handle boundary conditions source terms pollutants is explained, as well main differences present...
There are a wide variety of devices behaving essentially as flexible and elastic systems while interacting dynamically with fluids, usually water or air, under normal operating conditions. Interactions this kind involve double complexity the dynamics, go through large deformation due to flow actions, simultaneously, dynamics is strongly influenced by shape adopted systems. The present research adapts mathematical methods, still new field, represent ways dealing flows fluid in bidirectional...
Particle transport by fluid is probably one of the most difficult and involved subjects among dynamics, with many important issues in this field still to be fully understood. The main purpose work was advance capabilities computational dynamics (CFD) code caffa3d so include effective numerical modeling particle turbulent flow. An Eulerian mixture model selected wherein particles are not addressed individually but rather as a whole, incorporating their effect means an local viscosity....
Open source flow solver caffa3d.MBRi is applied in this work to solve the cases proposed SBC2012 CFD Challenge, offering an overall very cost effective solution. It found that cycle-averaged pressure drops are well represented by correspoding stationary cases, while peak systole drop values widly overestimated corresponding cases.
A model for representing different pollution sources in an Urban Environment is presented this paper. An in-house incompressible flow solver called caffa3d.MBRi was used and modified order to include the from chimneys, cars houses compute dispersion of pollutants simultaneously. Moreover, urban domains with a wide variety were simulated reaching promising results.
A general purpose fluid flow solver, caffa3d.MBRi, is presented which features a block structured framework to accommodate both flexible approach geometry representation and straightforward implementation of parallel capabilities through the MPI library. Representation complex geometries can be handled semi automatically combination body fitted blocks grids immersed boundary condition strategy over Cartesian grid blocks. The parallelization based on same framework, by means encapsulated...
