碩士 === 國立臺灣海洋大學 === 河海工程學系 === 98 === The wind tunnel experiments were conducted to study the flow and dispersion characteristics for a turbulent boundary layer flow over two consecutive embankments with different spaces. The upwind slope angle and down slope angle of the embankment was the same. Two slope angles of 27o and 45o were adopted. Two consecutive embankments were arranged with spaces of 0L, L, 2L, and 3L. Here L is the top surface length of the embankment. The flow and dispersion characteristics included the mean velocity, turbulence intensity, Reynolds stress, and dispersion parameters. Effects of the embankment slope angles and spaces between the two embankments on the flow and dispersion were investigated in the study.
