| Abstract: | The wave instability of convective boundary layers in a horizontal cylindrical layer of ethanol under the action of vertical
hamonic high-frequency vibration is studied. A strong destabilizing effect of the vibration on the stability of the convective
boundary layers is detected. In the plane of the gravity and vibration Rayleigh numbers (Ra and R
V
), the excitation limit of the wave instability is determined. The periods of the temperature oscillations caused by the waves
in the boundary layers near the inner and outer cavity boundaries are studied as functions of the Rayleigh numbers.
