The relative position of the secondary cylinder is defined by horizontal distance G and level Z between the two cylinders. As the secondary cylinder was shifted upstream, when it reached a certain gap, the base suction fell critically; the gap is referred to as "critical gap". To make clear the mechanism of the critical behavior, PIV(Particle Image Velocimetry) analysis was conducted in a water tank. It was proved that the shear-layer interaction changes significantly depending on level Z.}, pages = {51--57}, title = {下流円柱の接近に伴う上流円柱後流渦挙動のPIV解析}, volume = {32}, year = {2003}, yomi = {オダ, ジュンコ and オゾノ, シゲヒラ and ミヤギ, ヒロモリ and ワカスギ, ヤスオ} }
