3D ray tracing solver for communication blackout analysis in atmospheric entry missions
Poedts, Stefaan; Giangaspero, Vincent F.; Sharma, Vatsalya +4 more
During the atmospheric entry phase at hypersonic speed, the radio communication from/to a space vehicle can be disrupted due to the formation of a plasma sheath within the surrounding flow field. In order to characterize such communication blackout phases, this work presents a numerical methodology combining Computational Fluid Dynamic (CFD) simul…
Geliosphere - parallel CPU and GPU based models of cosmic ray modulation in the heliosphere
Solanik, Michal; Bobík, Pavol; Genči, Ján
We present Geliosphere, a numerical model of the modulation of cosmic rays in the heliosphere. The current version of Geliosphere implements the stochastic differential equation method to solve Parker's equation. Sets of 1D and 2D models of Geliosphere solve Parker's equation in a backward-in-time manner for 2D models and in a backward-in-time and…
