Nonsteady-state thermal convection in a spherical cavity

Three-dimensional axisymmetrical convection in a spherical cavity is examined. The general heat-transfer condition is stipulated on the boundary of the spherical cavity. A method of finite differences is used for the solution.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 4, pp. 118–124, July–August, 1970.The authors thanks G. Z.
