Abstract
Three-demensional laminer-flow in curved square channel has been investigated by using flow visualization technics. The hydrogen bubble method was applied to trace the flow. The flow velocity vecter was measured at five streamwise stations along the main flow direction. The flow intensity is of 1000 in Reynolds number and the channel is made of a 90° bend with curvature ratio of 2 having an inlet and outlet straight channel.
The result of measurement was compared with that of numerical analysis.
