%X Two-dimensional stationary laminar free convection in cavities obtained by rounding-off the angles of an initially square shape is studied numerically at the Rayleigh numbers of from 10^{4} to 5 · 10^{9} at the following values of the Prandtl number 0.03, 0.1, 0.71, 2, 5, and 10. It is found for the cavities with isothermal vertical and adiabatic horizontal walls that rounding-off of the angles with preservation of the length of isothermal portions leads to an increase in the Nusselt number to 20%. The strongest effect of rounding-off of the angles is in lowering the limit of stability of stationary convection.
