Numerical Modeling of the Thomson Ring in Stationary Levitation Using FEM-Electrical Network and Newton-Raphson
(Facultad de Ingeniería, 2016)
Modelling deltaic progradation constrained by a moving sediment source
(Int Assoc Hydraulic Research, 2013-06)
A physically-based moving boundary model of deltaic progradation is developed. Surface of the axially symmetric, inner delta is free to grow or shrink in time, while the sediment source is allowed to migrate along the ...
Numerical simulation of the flow around the ahmed vehicle model
(Planta Piloto de Ingeniería Química, 2009-10)
The unsteady flow around the Ahmed vehicle model is numerically solved for a Reynolds number of 4.25 million based on the model length. A viscous and incompressible fluid flow of Newtonian type governed by the Navier-Stokes ...
Gravitational field calculation in spherical coordinates using variable densities in depth
(Wiley Blackwell Publishing, Inc, 2019-09)
We present a new methodology to compute the gravitational fields generated by tesseroids (spherical prisms) whose density varies with depth according to an arbitrary continuous function. It approximates the gravitational ...
HIV risk and preventive interventions in transgender women sex workers
(Elsevier, 2015)
Worldwide, transgender women who engage in sex work have a disproportionate risk for HIV compared with natal male and female sex workers. We reviewed recent epidemiological research on HIV in transgender women and show ...
Study of the state a Francis turbine
(Politechnika Gdanska, Wydzial Oceanotechniki i Okretownictwa, 2013-04-01)
This paper presents a methodology to evaluate the technical state of a Francis turbine by shaft rotor dynamic simulation. There are several rotor dynamic criteria that define the technical state of a turbo-machine. To feed ...
Numerical modeling of phase change materials using simusol software
(Pergamon-Elsevier Science Ltd, 2019-02-07)
Thermal storage systems with phase change materials offer a high density of energy with a moderate temperature variation as well as the possibility to keep the inner temperature within a comfort range. To achieve this goal, ...
Mechanical Response of High Strength Fibre Reinforced Concrete Under Extreme Loads
(Springer Science and Business Media B.V., 2021-01)
High Strength Fibre Reinforced Concrete (HSFRC) presents great advantages when compared with conventional concrete under static loads and thus, it constitutes a promising material to withstand extreme loads. An experimental ...
