Large and sharp fluctuation of velocity though occasional, designated 'spike', found in the wake, tends to distribute itself transversely much wider than steady small fluctuations which contribute most to the r.m.s.

With the cylinder set rather far from a plate (parallel to the flow), for its boundary layer transition to turbulence, such spikes are found to play the dominant role.

presented.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
