Flow structure around a submerged spur dike
WebAbstract:A spur dike is a structure that projects from a stream bank into the river channel and causes a redirection of ow away from the bank toward the tip of the spur dike. Construction of a spur dike against the ow causes signi cant changes in ow pattern in the channel. In this study, the ow pattern around a 25% submerged T-shaped spur dike in a http://www.flow3d.com/wp-content/uploads/2014/04/Numerical-investigation-of-the-effect-of-Froude-number-on-flow-pattern-around-a-submerged-T-shaped-spur-dike-in-a-90%C2%BA-bend.pdf
