We conduct direct numerical simulations based on the Boussinesq approximation for a forcedly-oscillating cube under the zero-gravity environment, at vibrational Rayleigh number [Raη] = 5.0×10[4] – 1.1×10[5], Plandtl number [Pr] = 7.1 (water) and non-dimensional forced-oscillating frequency [ω] = 1.0×10[0] – 2.0×10[2]. The direction of the forced sinusoidal oscillation is parallel to the temperature gradient. From obtained consequtive series of computations, it appears that the first POD modes account for the transient process on spacial flow structures during one forcing period. The first POD modes well correspond to the steady and laminar flow structures which appear in a non-oscillating cube under the terrestrial environment. The expansion coefficient is useful in particular, as we could predict the transient process of the dominant flow structures.","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[Raη][ω][Pr]は斜体文字、[4][5][0][2]は上付き文字、[η]は下付き文字","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2017.0000014215","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学ハリス理化学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Harris
