The Cooling of a Lava Flow Spreading over a Flat Surface / E. A. Vedeneeva, O. E. Melik, and I. S. Utkin. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2017. № 4. P. 36-40 [Moscow Univ. Mech. Bulletin. Vol. 72, N 2, 2017. P. 84-88].

The cooling of a lava flow modeled by a viscous incompressible fluid spreading over a flat surface is considered. In order to model the free surface, a known analytical solution is used in the thin-layer approximation. The thermal boundary layer thickness is determined and the evolution of thermal fields in the lava profile is studied.

Key words: volcanic eruptions, lava flows.
