The direction of the forced sinusoidal oscillation is parallel to the temperature gradient inside the cube. As a result, five kinds of flow structures S2, S4, S5, S6 and Sα appear in the tested ranges of vibrational Rayleigh number Ra[η] and non-dimensional forced-oscillation frequency ω. The Sα consists of a pair of trident currents. Whenever it is not conductive but convective for ω < 5.0×10[2], convective motion always starts with the S4 from the rest at each forcing cycle. The authors find out the optimum frequency where the amplitude of a spatially-averaged kinetic energy attains the maximum at each Ra[η]. At the optimum frequency, flow structure is always characterised by the S4. So, the optimum frequency can be related with the S4. In addition, the authors show the occurrence condition for convection as a function of Ra[η] and ω, and the boundary for the quasi-steady approximation which is permissible at ω ≲ 10[0].","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_13":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"抄録中の[2][0]
