Title: ANALYSIS OF BAFFLE WALL GAP IN THE DESIGN OF STILLING BASIN MODEL
Abstract: This paper investigates the gap of baffle wall in stilling basin design for the enhancement of energy dissipation in order to protect the downstream structures from excessive scouring. Experiments have been carried out by keeping the baffle wall at same location for Froude numbers 3.85, 2.85 and 1.85 to evolve the new stilling basin model by changing the gap beneath the wall above the basin. Performance of outlet basins having baffle wall of at same location with varying the gap were evaluated based on dimensionless number called as performance index (PI), which is the ratio of grains Froude number to scour index. Higher values of PI indicate better performance of the basin. It is concluded that by placing the appropriate baffle wall size at suitable location with proper gap, the efficiency of basin increases.
