What is the Dataheat Flow Density & How does it work?
Geothermal heat flow density quantifies the amount of thermal energy moving upward through a unit area of the Earth’s crust. It is a key parameter for assessing geothermal resource potential and understanding the thermal regime of the lithosphere. The heat flow density (q) is calculated as the product of the rock’s thermal conductivity (k) and the vertical temperature gradient (Ξ”T/Ξ”z). Higher conductivity or steeper gradients increase the upward heat flux. Accurate measurement of k and the temperature gradient requires borehole logging and laboratory analysis. The resulting q values are typically expressed in watts per square meter (WΒ·m⁻²) and guide the design of geothermal power plants.
q = k times frac{Delta T}{Delta z}
k = thermal conductivity (W·m⁻¹·K⁻¹)
Ξ”T/Ξ”z = temperature gradient (KΒ·m⁻¹)
