Abstract

Based on steady-state heat metering method, a measurement system is developed, which can be used to test the effective conductivity of a granular system under different temperature and vacuum degree. Using this measurement system, experiments for HIT-LS1# lunar soil simulant are conducted. The results show that the effective thermal conductivity of the lunar soil simulant increases with temperature, and decreases with the increase in vacuum degree. Vacuum degree has on obvious impact on the effective thermal conductivity, especially in the case of high vacuum.
