After landing in the Utopia Planitia, Tianwen-1 formed the deepest landing crater on Mars,
approximately 40 cm deep, exposing precious information about the mechanical properties …

A three-dimensional mixed modal discontinuous Galerkin (DG) method based on tetrahedral
meshes was developed for simulating all flow regimes from subsonic to hypersonic rarefied …

The interactions between rocket exhaust plumes and the surface of extraterrestrial bodies
during spacecraft landings involve complex multiphase flow dynamics that pose significant …

In recent years, prominent spacefaring nations have redirected their attention towards the
Moon as a potential avenue for economic prospects and as a pivotal waypoint for extended …

A novel, two-way coupled, dusty-gas flow model has been developed in the direct simulation
Monte Carlo (DSMC) framework and employed for the dust-dispersion study on lunar …

This study presents a numerical investigation of rocket plumes carrying regolith particles in
the context of the lunar environment (gravity and vacuum conditions). We investigated two …

The plume-surface interaction that occurs as a result of a variable-thrust engine exhaust
plume impinging on soil during landings is critical for future lunar mission design. Unique …

Advanced spacecraft development requires high-performance thermal protection systems
composed of materials with high particle-erosion resistance. In this study, a particle-erosion …

Planar laser-induced fluorescence (PLIF) was applied for the first time in the 20-ft vacuum
chamber at the Marshall Space Flight Center to visualize the plume-surface interaction (PSI) …

We investigate the flow physics of non-equilibrium gases in interaction with solid particles in
a microscale shock tube and the collection efficiency in the jet impingement on a permeable …
