Two-dimensional Navier--Stokes simulation of deformation and break up of liquid patches

, 1995
The large deformations and break up of circular 2D liquid patches in a high Reynolds number (Re=1000) gas flow are investigated numerically. The 2D, plane flow Navier--Stokes equations are directly solved with explicit tracking of the interface between ...

Regularization modeling for large-eddy simulation [PDF]

, 2002
A new modeling approach for large-eddy simulation (LES) is obtained by combining a `regularization principle' with an explicit filter and its inversion.

Siewert solutions of transcendental equations, generalized Lambert functions and physical applications

Open Physics, 2018
Several classes of transcendental equations, mainly eigenvalue equations associated to non-relativistic quantum mechanical problems, are analyzed. Siewert’s systematic approach of such equations is discussed from the perspective of the new results ...

Algorithm for numerical integration of the rigid-body equations of motion [PDF]

, 1998
A new algorithm for numerical integration of the rigid-body equations of motion is proposed. The algorithm uses the leapfrog scheme and the quantities involved are angular velocities and orientational variables which can be expressed in terms of either ...

The Influence of Metallicity on Star Formation in Protogalaxies

, 2007
In cold dark matter cosmological models, the first stars to form are believed to do so within small protogalaxies. We wish to understand how the evolution of these early protogalaxies changes once the gas forming them has been enriched with small ...

The Jacobi-Maupertuis Principle in Variational Integrators [PDF]

, 2009
In this paper, we develop a hybrid variational integrator based on the Jacobi-Maupertuis Principle of Least Action. The Jacobi-Maupertuis principle states that for a mechanical system with total energy E and potential energy V(q), the curve traced out by

New Insights into Traffic Dynamics: A Weighted Probabilistic Cellular Automaton Model

, 2007
From the macroscopic viewpoint for describing the acceleration behavior of drivers, this letter presents a weighted probabilistic cellular automaton model (the WP model, for short) by introducing a kind of random acceleration probabilistic distribution ...

A method for solving systems of non-linear differential equations with moving singularities [PDF]

, 2002
We present a method for solving a class of initial valued, coupled, non-linear differential equations with `moving singularities' subject to some subsidiary conditions.
