内容記述 | Glass beads have often used to simulate the planetary regolith. Effective thermal conductivity has been measured for spherical glass beads in several diameters. There are some data which were obtained at low air pressures (about 1 Pa) to evaluate heat transfer rates through the contact regions of adjacent solid particles, and at pressure from 1 to 10(exp 5) Pa, to ascertain the effects of free molecule conduction. Geometrical considerations were used to develop equations for predicting the effect of pressure on effective conductivity. Masamune and Smith (1963), which involve only one arbitrary constant, agreed well with available data. However their theory cannot predict the thermal conductivity of the other data in the ambient pressure (approximately 10(exp 5) Pa).
