A mathematical model of convective cell motion in the mantle under exposure to a heat source at the mantle--core boundary
An algorithm for numerically solving the vector problem on the modeling of the convective motion of matter in the Earth’s mantle was built and implemented. A 2D model of convective cell formation in the mantle was considered with a moving heat source at the boundary with a core that generates an upwelling flow of the mantle substance. The motion of the heat source is possible only along the core--mantle boundary. If the heat source is absent, the system is conservative. The mantle was modeled as an incompressible fluid with constant viscosity.
