Numerical And Experimental Study Of Anisotropic Effective Thermal Conductivity Of Particle Beds Under Uniaxial Compression, Jingwen Mo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Planetary heat flow is of great interests to planetary scientists, which can be used to determine the history and current status of pianetary bodies. Thermal conductivities of planetary bodies are generally measured using long needle-like probes inserted into planet's surface, which measure the horizontal effective thermal conductivity (parallel to the planetary surface). The vertical effective thermal conductivity (perpendicular to the planetary surface), used for heat flow calculation, is assumed to be the same as the horizontal effective thermal conductivity. However, ETC of particle beds is known to be an anisotropic property under low compressive pressures.
