Three-dimensional finite element analysis of MHD duct flow by the penalty function formulation
(Institute of Electrical and Electronics Engineers (IEEE), 2001-09-01)
A numerical scheme based on the Finite Element Method (FEM) is presented to calculate the full solution of a three-dimensional steady magnetohydrodynamic (MHD) flow with moderately high Hartmann numbers and interaction ...
Simulation of unsteady laminar flow in models of terminal aneurysm of the basilar artery
(TAYLOR & FRANCIS LTD, 2005-05)
Blood flow dynamics play an important role in the pathogenesis and treatment of intracranial aneurysms. The evaluation of the velocity field in the aneurysm dome and neck is important for the correct placement of endovascular ...
Análisis de estabilidad dinámica en chumacera híbrida con CFD
(2011-06-30)
This work analyzes the flow inside of a hybrid journal bearing with and without pressurization on the finite volume software ANSYS-CFX. The hydrodynamic lubrication equations needed are analyzed superficially, as well as ...

O presente trabalho apresenta um estudo acerca das soluções analíticas e numéricas para algumas classes de escoamentos incompressíveis, isotérmicos e laminares de fluidos Newtonianos no estado estacionário ou transiente. ...
Development of a physics-informed machine learning method for aerodynamic and fluids simulation
(Universidad de los AndesIngeniería MecánicaFacultad de IngenieríaDepartamento de Ingeniería Mecánica, 2021)
An implementation of a non-data driven Physics Informed Neural Network (PINN) for simulation of steady state fluid flow is presented. Through the use of deep convolutional neural networks, the velocity and pressure fields ...
Coupled CFD Shape Optimization for aerodynamic profiles
(Universidad EAFITMaestría en IngenieríaEscuela de Ingeniería, 2015)
The present document deals with the optimization of shape of aerodynamic profiles -- The objective is to reduce the drag coefficient on a given profile without penalising the lift coefficient -- A set of control points ...
2D lid-driven cavity flow simulation using GPU-CUDA with a high-order finite difference scheme
(Springer, 2014-10)
El alto paralelismo y el bajo costo de las unidades de procesamiento gráfico (GPU) han atraído el interés de científicos e ingenieros que requieren una alta potencia computacional con una modesta inversión. Este trabajo ...
Drops with non-circular footprints
(American Institute of Physics, 2016-04)
In this paper we study the morphology of drops formed on partially wetting substrates, whose footprint is not circular. These drops are consequence of the breakup processes occurring in thin films when anisotropic contact ...
Time-dependent mass-transfer behaviour under laminar and turbulent flow conditions in rotating electrodes: A CFD study with analytical and experimental validation
(Pergamon-Elsevier Science Ltd, 2019-07)
Results of numerical calculations and their comparison with analytical expressions or experimental data under laminar and turbulent flow conditions are reported. It is predicted the transient and steady-state behaviour of ...
