Nusselt-Rayleigh number scaling for spherical shell Earth mantle simulation up to a Rayleigh number of 10 9
An investigation of the power law relationship between Nusselt number (Nu) and Rayleigh number (Ra) for Earth's convecting mantle is presented. The Nu(Ra) relationship was calculated from the results of a model with three dimensional spherical geometry and free slip boundary conditions. Both basally and internally heated convection has been examined. For Nu (Ra) = a Raβ, β was found to be 0.294 ± 0.004 for basally heated systems, which is lower than the value of 1/3 suggested by conventional...[Show more]
