Numerical Comparison of Two Runners for Gravitational Vortex Turbine

open access: yesEngineering Transactions, 2021
The main purpose of this study is to compare numerically the torque generated by two runners for a gravitational vortex turbine. One of the runners was an H-Darrieus turbine with the rotational flow into the chamber that helped to decrease its negative ...

Vortex profiles and vortex interactions at the electroweak crossover [PDF]

open access: yes, 1999
Local correlations of Z-vortex operators with gauge and Higgs fields (lattice quantum vortex profiles) as well as vortex two-point functions are studied in the crossover region near a Higgs mass of 100 GeV within the 3D SU(2) Higgs model.

On Vortex Methods

open access: yesSIAM Journal on Numerical Analysis, 1985
Error estimates for fully discretized two- and three-dimensional vortex methods for Euler's equations are given. An elementary proof of the consistency result by \textit{G. H. Cottet} [Thèse de 3ième cycle, to appear], together with its three-dimensional analogue is presented. Following the convergence theory of \textit{J. T.
