ESTIMATION OF THE AMPLITUDE OF NONLINEAR "ANTICONVECTION"

In systems consisting of two immiscible liquids in the gravity force fi eld, convective instability may set in not only on heating from below, but also on horizontal-homogeneous heating from above, i.e., on stable density stratifi cation of each of the media. In a number of previous works, a linear theory of this type of instability ("anticonvections") has been developed. In the present work, analytical estimates of the characteristics of fi nite-amplitude anticonvection have been made for the fi rst time for the limiting case of neutral stratifi cation of one of the media
