Journal ArticleDOI
The effect of damage accumulation behaviour on ablation thresholds and damage morphology in ultrafast laser micro-machining of common metals in air
TL;DR: In this paper, the ablation threshold fluence depends on the number of pulses applied to the same spot, and the strength of this dependence is governed by the incubation coefficient, S, which has been determined along with the single-shot threshold, φ th (1), for all the metals studied.
Proceedings ArticleDOI
Ablation thresholds in ultrafast laser micromachining of common metals in air
TL;DR: In this article, the authors studied the ablation of metal targets in air with femtosecond laser pulses, and showed that the intensity of the laser pulses depends logarithmically on the optical penetration depth.
Journal ArticleDOI
Aerodynamic drag in cycling pelotons: new insights by CFD simulation and wind tunnel testing
Bert Blocken,Bert Blocken,Thijs van Druenen,Yasin Toparlar,Fabio Malizia,Paul Mannion,Paul Mannion,Thomas Andrianne,Thierry Marchal,Geert-Jan Maas,Jan Diepens +10 more
TL;DR: In this article, high-resolution CFD simulations are performed with the RANS equations and the Transition SST-k-ω model to investigate the drag reductions in two pelotons of 121 cyclists.
Journal ArticleDOI
STEM (scanning transmission electron microscopy) analysis of femtosecond laser pulse induced damage to bulk silicon
TL;DR: In this paper, the structural changes that take place in wafer grade silicon when it is micro-machined with ultra-short laser pulses of 150 fs duration were reported.
Journal ArticleDOI
Improving CFD prediction of drag on Paralympic tandem athletes: influence of grid resolution and turbulence model
Paul Mannion,Paul Mannion,Yasin Toparlar,Bert Blocken,Bert Blocken,Magdalena Hajdukiewicz,Thomas Andrianne,Eoghan Clifford +7 more
TL;DR: In this article, the influence of the CFD grid topology and the turbulence model on the aerodynamic forces on pilot and stoker was analyzed and compared with wind-tunnel measurements.
