Convective motions of a viscoplastic fluid in a rectangular region

Two-dimensional convective motion of a viscoplastic fluid in a long horizontal cylinder of square section heated on the side was studied numerically by the author in [1]. In the present paper, the problem of convection of a viscoplastic fluid in a rectangular region is solved numerically.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 5, pp. 141–144, September–October, 1979.I should like to thank G.
