Present house exploration goals to determine everlasting buildings on the Moon, Mars, and finally different planetary our bodies. Profitable lunar missions rely on understanding lunar regolith, the granular materials protecting the Moon’s floor, whose conduct is ruled by low gravity, vacuum situations, particle irregularity, electrostatic results, and excessive thermal environments. This webinar will deal with two related modeling issues associated to lunar regolith: plume–regolith interplay throughout lunar landings and induction heating of porous regolith for thermal processing and melting. Collectively, these issues present how simulation with the COMSOL Multiphysics® software program may help engineering and analysis groups predict, management, and make the most of granular lunar materials.
The primary a part of the discuss will deal with plume–regolith interplay. Throughout spacecraft landings, underexpanded rocket exhaust plumes impinge on the floor, producing compressible stream buildings, erosion, particle ejection, and doable floor harm. Excessive-speed mud can cut back visibility and threaten astronauts, tools, and close by property. These points are particularly vital for Artemis and future missions involving repeated landings and bigger spacecraft. Modeling the coupled gas-particle response offers perception into landing-site security, erosion patterns, ejecta trajectories, and mitigation methods.
The second a part of the webinar will study induction heating of porous regolith, the place electromagnetic power is transformed into warmth to boost temperature, drive section change, and doubtlessly soften lunar soil. The dialogue will emphasize temperature-dependent porous media properties, latent warmth remedy, soften fraction evolution, and the variations between constant-property and piecewise-property fashions. By connecting these research, the webinar will exhibit how COMSOL-based workflows can quantify stream fields, particle transport, thermal response, and phase-change conduct whereas supporting safer operations, regolith processing applied sciences, and the event of future house infrastructure.
