✦ Synopsis

The problem of initiation of thermal convection in rectangular cavities filled with viscoplastic material is considered. A two-sided asymptotic expansion is combined with numerical modelling in order to obtain an expression for the critical yield number, which is valid for the entire range of the cavity's aspect ratio.
