چکیده
H2O transport through a packed bed of Johnson Space Center number 1A (JSC-1A) lunar regolith simulant was examined at relevant temperatures and pressures for in-situ resource utilization (ISRU) on the Moon. Experimentation conducted over range from 50 to 2065 Pa ∼350 K, corresponding Knudsen numbers 0.3 &lt; Kn 11. Pressure temperature conditions were toward ISRU technologies. A piecewise function used evaluate transition regime flows. The model utilized that predicted point between advective 1.66 ± 0.61 tortuosity shape parameter 0.736 0.13 determined non-linear regression, diffusivities 10.62 cm2·s−1, 10.40 9.04 cm2·s−1 beds JSC-1A with porosities 0.388, 0.385, 0.365, respectively. experimental measurements, methodology, modeling provide useful information technologies involving volatiles (e.g., thermal extraction H2O).

متن کاملDielectric Spectroscopy for Scientific and Resource Characterization of Lunar Regolith
Introduction: Dielectric spectroscopy (DS) can noninvasively detect electrical properties over a wide frequency range (1 mHz – 10 kHz) at depths ranging from 10s cm to 10s m. Electrical properties vary directly with density and mineralogy. Therefore, DS can determine the subsurface distribution of water ice, adsorbed water, ilmenite, and possibly Fe. Understanding the subsurface distribution of...
