[Submitted on 17 Apr 2024] Title:arcjetCV: an open-source software to analyze material ablation View a PDF of the paper titled arcjetCV: an open-source software to analyze material ablation, by Alexandre Quintart and 2 other authors View PDF HTML (experimental) Abstract:arcjetCV is an open-source Python software designed to automate time-resolved measurements of heatshield material recession and recession rates from arcjet test video footage.
Laboratory measurements of B(x,t) in a volume enclosing portions of two arched flux ropes show flux rope collimation driven by gradients in axial current density. These measurements verify the three predictions of a proposed MHD collimation mechanism: 1) axial magnetic forces exist in current channels with spatially varying minor radius, 2) these forces can drive counter-propagating axial flows, 3) this process collimates the flux rope.
