Abstract

This paper considers the problem of thermal convection of a viscous incompressible fluid in a cylindrical elementary convective cell with a conically deep bottom and solid boundary conditions. The Stokes functions are constructed in a cylindrical convective cell, as well as on the conical deepening of the cell bottom. Based on the Fujiwara effect, we obtained model distributions of Stokes current lines in a cylindrical elementary convective cell having a conically deepened bottom and solid edges.

 

Keywords: cylindrical elementary cell, heat convection, conical cavity, solid boundary conditions, viscous incompressible liquid, Fujiwhara effect
