| Abstract: | A numerical study has been made of the shapes of convective motion of a gas in a cubic cavity heated from below. The motion is generated by heating of the base of the cavity in accordance with a definite law. The evolution of the shapes of the motion up to the establishment of a final state has been followed. For the three basic forms of motion the regions of stability, the coefficients of heat transfer through the cavity, and the critical Rayleigh numbers have been determined.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 21–26, January–February, 1984.I am grateful to L.
