摘要：

We report an experimental investigation of He II forced flow over a cylindrical obstacle by a flow visualization technique that uses micron scale solid hydrogen particles. It was found in the range of Reynolds numbers studied, 1500 < Re-d < 11 500, that the flow pattern has a tendency to form a wake with a dynamic separation point similar to that in classical fluids. Furthermore, we did not confirm the existence of large-scale turbulent structures both upstream and downstream of the cylinder as have been observed in He II thermal counterflow across the cylinder at the same range of Reynolds numbers.
