Control of the convective equilibrium stability of a fluid heated from below

Potentially unstable equilibrium is stabilized by means of a method of control based on the single-channel feedback principle using the characteristics of the solution of the complete nonlinear thermal convection equations. The convection equations are solved by a finite-difference method.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 4, pp. 6–11, July–August, 1990.
