WebThe energy reaching the surface of the Earth from within can be measured to get heat flux, q.. q = - k dT/dz . Units of heat flux = Wm-2 which is equivalent to Js-1 m-2, and k is the thermal conductivity (Wm-1 K-1). The average heat flow from the Earth gives a q of approximately 0.08Wm-2 (equivalent to 80mWm-2).. But the flow is very uneven. WebThe double-ellipsoid heat source, originally proposed by Goldak et al. (1984), has been used in many papers, e.g., Leung and Pick (1986), Das et al. (1993), and Michaleris (1997). The heat input is defined separately over two regions, see Figure 24. A comparison with measured temperatures is shown in Figure 25.
