Transient computations using the natural stress formulation for solving sharp corner flows
(Elsevier B.V., 2017-11-01)
In this short communication, we analyse the potential of the natural stress formulation (NSF) (i.e. aligning the stress basis along streamlines) for computing planar flows of an Oldroyd-B fluid around sharp corners. This ...
Application of the natural stress formulation for solving unsteady viscoelastic contraction flows
(Elsevier B.V., 2019-07-01)
We present a numerical scheme for a previously unexploited formulation of the equations for unsteady viscoelastic flow. The formulation aligns the polymer stress along particle paths/streamlines, utilising the characteristic ...
Fourth-order method for solving the Navier-Stokes equations in a constricting channel
(1997-11-30)
A fourth-order numerical method for solving the Navier-Stokes equations in streamfunction/vorticity formulation on a two-dimensional non-uniform orthogonal grid has been tested on the fluid flow in a constricted symmetric ...
A study of a numerical solution of the steady two dimensions Navier-Stokes equations in a constricted channel problem by a compact fourth order method
(Elsevier B.V., 2003-12-31)
We present a numerical solution for the steady 2D Navier-Stokes equations using a fourth order compact-type method. The geometry of the problem is a constricted symmetric channel, where the boundary can be varied, via a ...

HIDRODINÁMICA DEL ACERO LÍQUIDO DURANTE EL LLENADO DE LA OLLA.
(2012-03-12)
The computational approach of this model involves the solution of Navier-Stokes Equations for a multiphase flow through an explicit method using the Volume of Fluid (VOF) model in order to define sharp interfaces, among ...
Métodos de fronteira imersa para corpos esbeltos: implementação e validação

Diverter damper force analysis and stress intensity factors for its double fillet welds by boundary element method
(2021-03-01)
Mechanisms usually transmit power by welded links into a shaft. Should this weld be partial, like fillet welds, there will be an area of stress concentration that could behave like a crack due to sharp corners. These can ...
