 note = {本研究では，重力場および微小重力場の加振及び無加振状態における立方体容器内部の水の対流を考え，一面加熱，対面冷却，側面完全熱伝導を境界条件とし，プラントル数Pr=7.1として，ブシネスク近似を用いて有限差分法による数値解析を行う．本研究では特に，層流定常状態において新たに発見した構造について述べる．この流れ構造は一対となる三叉の上昇流と下降流とで構成される流れ構造である．この構造は，地上重力場無加振定常状態・微小重力場/地上重力場での強制加振状態の三つの場合で安定的に生じる．, We numerically investigate thermal convection in a cubic cavity. Thermal convection in a cube is induced heating from one wall and chilling from its opposite wall in the terrestrial-gravity and zerogravity fields with and without a sinusoidal modulation. The gravity and its modulation are parallel to the temperature gradient. An incompressible fluid with Prandtl number Pr = 7.1 (water) is considered and hence the Boussinesq approximation is used. We have reported a new flow structure which consists of a pair of trident currents. This previously-unidentified flow is not so weakly-stable but rather durable, and can be observed not only in a stationary cube under the terrestrial gravity, but also in an oscillating cube under the terrestrial gravity and zero gravity., application/pdf},
