TO FIND THE OPTIMUM SPACING OF GROYNES THROUGH ANSYS

Abstract

Groynes are the structure used for protection of river banks from erosion caused due to meandering rivers. In this project various flow perimeters around the groynes and optimum spacing for the groynes is analysed with the help of ansys fluent. In this project various model of groynes are studied for different spacing in a compound channel having symmetrical flood plains. There are four different models in which spacing between the models is varied and then for different velocities the optimum spacing between the different groynes is found out. Variation of velocities at inlet and around the groynes is also discussed in the report. Following four models of the groynes are studied : Groynes with D=1,Groynes with D=2, Groynes with D=3, Groynes with D=4, Here “D” is the ratio of spacing between the groynes and the length of the groynes.
