Abstract: | A vibrating convective flow around a uniformly heated sphere in weightlessness conditions is studied theoretically for circularly
polarized vibrations. It is found that the fluid motion has the form of two jets spreading from the sphere in opposite directions
along the symmetry axis, perpendicular to the vibration polarization plane. For large characteristic temperature gradients,
the flow becomes self-similar. The equations describing thermovibrational convection in the boundary layer approximation are
derived. A class of self-similar solutions for a point heat source is found. The results obtained on the basis of the full
equations and in the boundary layer approximation are compared. |
