%X Two-dimensional steady laminar free convection in cavities produced by rounding-off of initially square corners is studied numerically at the Rayleigh numbers of from 10^{4} to 5·10^{9} at 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 corners (the length of isothermal portions being preserved) leads to an increase in the Nusselt number up to 20%. The strongest effect of rounding-off of the corners is in lowering the limit of stability of steady convection.
