WebHeat conduction in non-homogeneous anisotropic media. In general, the study of heat conduction is based on several principles. Heat flow is a form of energy flow, and as such it is meaningful to speak of the time rate of flow of heat into a region of space. The time rate of heat flow into a region V is given by a time-dependent quantity q t (V). WebGlobal heat flow. In it's simplist form, the rate of heat flowing out of the Earth is calculated by Q = − λ δ T δ z , where λ is thermal conductivity, an intrinsic physical property of a given rock type, and δ T the temperature gradient over a given depth interval δ z. In this equation Q has units W m − 2, however, when referring to ...
