Numerical Simulations for Fuel Aircraft Management System [PDF]
INCAS Bulletin, 2019 The Fuel Management Systems for civil aircrafts have a direct impact on the airlines profitability, competitiveness and sustainability, because the fuel represents the highest cost for airlines, on average 32% of overall operating costs; extra costs can ...

Numerical simulations of ICME–ICME interactions
Journal of Space Weather and Space Climate, 2019 We present hydrodynamical simulations of the interaction of Coronal Mass Ejections (CME) in the Interplanetary Medium (IPM). In these events, two consecutive CMEs are launched from the Sun in similar directions within an interval of time of a few hours ...

Lifetimes of Rogue Wave Events in Direct Numerical Simulations of Deep-Water Irregular Sea Waves
Fluids, 2019 The issue of rogue wave lifetimes is addressed in this study, which helps to detail the general picture of this dangerous oceanic phenomenon. The direct numerical simulations of irregular wave ensembles are performed to obtain the complete accurate data ...

Conserving Local Magnetic Helicity in Numerical Simulations
The Astrophysical Journal, 2023 Magnetic helicity is robustly conserved in systems with very large magnetic Reynolds numbers, including most systems of astrophysical interest, and unlike kinetic and magnetic energy, it is not dissipated at small scales.

Incoherent signature of internal tides on sea level in idealized numerical simulations
, 2015 The nonpersistent phase relationship between internal tides and astronomical forcings, also known as incoherence, has been identified as a major question in the context of future wide‐swath satellite altimetry.

AbstractSeveral of the numerical simulation exercises proposed in the following chapters require step-by-step raytracing through the optical elements concerned, for diverse reasons, depending on the problem. The raytracing code Zgoubi is used and provides the necessary tooling for this numerical solution of particle and spin motion in electric and/or ...
