  • For the interaction between the regolith particles raised by lunar lander and plume, the main factors of regolith particles force in the plume are analyzed. The formula and scope of the drag, lift and gravity forces on regolith particles are also discussed. These forces were computed by magnitude analysis, and the main forces impacting the lunar soil particle motion and spatial distribution are analyzed. Particle Reynolds number, Knudsen number and the porosity, related to the inertia correction factor fI, surface slip correction factor fC and the correction factor fF affected by the surrounding particles, in the plume field distributions were calculated, and effects of the three correction factors of lunar soil particle velocity and spatial distribution are also discussed. Results show that the longitudinal velocity of lunar soil particles and the maximum height of the lunar regolith particles can raise decreases slightly after fI and fF correction, while the impact of fC correction is not obvious.
