Investigation on heat transfer of solar-sintered regolith for lunar construction

The thesis provides a feasible pathway to simulate the radiation and heat transfer of concentrated solar sintering systems, which can be a promising technology used for lunar habitat construction. The work contributes to the body of knowledge by developing a new thermal conductivity model of lunar soil after sintering, since previous studies mostly ignored the effect of high-temperature processing, combining the radiation penetration inside the porous material when it is heated, and characterizing the heat transfer mechanism of sintered lunar soil bed by reproducing the micro-structure and thermal conductivity evolution of the powdered material during the high-temperature treatment.
