多重解テイラー渦におけるモードの形成条件 : 両端が固定の場合

概要

The Taylor vortex flow exhibits several flow patterns (modes) under the same conditions at small aspect ratios. The primary mode that is formed by increasing Re gradually from zero has a unique pattern with two normal cells having inward flow direction on the plate, and the secondary modes that are formed by increasing Re rapidly have several flow patterns with the normal cell or one or two anomalous cells that flow outward on the end plate. We used the flow visualization technique for the Taylor vortex flow and counted the number of modes appearing according to the various ways of increasing Re. The entropy was calculated, and the complication of the bifurcation of the modes was clarified. Finally, the processes of the formation of modes were illustrated and discussed.
