A finite-difference scheme for the direct simulation of the incompressible time-dependent
three-dimensional Navier-Stokes equations in cylindrical coordinates is presented. The …

This book deals with the simulation of the incompressible Navier-Stokes equations for
laminar and turbulent flows. The book is limited to explaining and employing the finite …

There is large uncertainty in the radiative forcing induced by aircraft contrails, particularly
after they transform to cirrus. It has recently become possible to simulate contrail evolution …

A particle method is presented for computing vortex sheet motion in three-dimensional flow.
The particles representing the sheet are advected by a regularized Biot–Savart integral in …

Vortex loops are compact toroidal structures wherein fluid rotation forms a closed loop
around a fictitious axis, manifest in many natural occurrences. These phenomena result from …

This paper presents a highly efficient parallel particle–mesh (PPM) library, based on a
unifying particle formulation for the simulation of continuous systems. In this formulation, the …

Starting flow through a nozzle or orifice typically results in the transient formation of a
leading vortex ring and trailing jet. Experiments are conducted to investigate the dynamics of …

A new combination of vortex-in-cell and parallel fast multipole methods is presented which
allows to efficiently simulate, in parallel, unbounded and half-unbounded vortical flows …

Direct numerical simulation is used to study the temporal development of single vortex rings
at various Reynolds numbers and core thicknesses. Qualitative differences between the …

A global stability analysis of Kelvin's vortex ring to three-dimensional disturbances of
infinitesimal amplitude is made. The basic state is a steady asymptotic solution of the Euler …
