Laser-guided lightning

Marcos Rubinstein, Antonio Sunjerga, Amirhossein Mostajabi, Jean-Pierre Wolf, Clemens Herkommer, Pierre Walch, Thomas Produit, Victor Moreno

Lightning discharges between charged clouds and the Earth’s surface are responsible for considerable damages and casualties. It is therefore important to develop better protection methods in addition to the traditional Franklin rod. Here we present the fir ...

Lightning return stroke current radiation in presence of a conducting ground: 2. Validity assessment of simplified approaches

In this paper, the developed formulation, which we shall call the “reference” one, is used to assess the validity of the most popular simplified approach for the calculation of the lightning electromagnetic field over a conducting earth, namely, the Cooray ...

Use of genetic algorithms to extract primary lightning current parameters

José-Luis Bermudez

In this paper, we propose a method based on genetic algorithms to extract primary lightning return stroke current parameters from currents measured using instrumented towers, including the possibility of contamination by multiple reflections occuring along ...

On the use of shock-capturing schemes for large-eddy simulation

Michel Deville, Pascal Comte, Michele Mossi

"Numerical simulations of freely decaying isotropic fluid turbulence were performed at various Mach numbers (from 0.2 to 1.0) using known shock-capturing Euler schemes (Jameson, TVD-MUSCL, ENO) often employed for aeronautical applications. The objective of ...
