Spectral element discretization of the circular driven cavity. Part IV: The Navier-Stokes equations
(2004)This paper deals with the spectral element discretization of the Navier-Stokes equations in a disk with discontinuous boundary data, which is known as the driven cavity problem. The numerical treatment does not involve any ...

Viscoplastic Poiseuille flow in a rectangular duct with wall slip
(2014)We solve numerically the Poiseuille flow of a Herschel-Bulkley fluid in a duct of rectangular cross section under the assumption that slip occurs along the wall following a slip law involving a non-zero slip yield stress. ...

Worldline path integral for the massive Dirac propagator: A four-dimensional approach
(1999)We simplify and generalize an approach proposed by Di Vecchia and Ravndal to describe a massive Dirac particle in external vector and scalar fields. Two different path integral representations for the propagator are derived ...
