Abstract: | The sluice gates are used in controlling the flow of water through the canals and irrigational structures. Humps/sills are installed in canals and channels for reducing the height of gates and they are also used for energy dissipation. Sluice gates are mainly used in irrigation structure, humps/prismatic sills under gates has positive effect on flow performance under the gate and reduce its height. An experimental study in a laboratory flume of delhi technological university (delhi) is carried out to study submerged flow passing the opening between the hump and the gate. Three different heights of humps are used for this project. The basic principles of analysis are employed to correlate between the hydraulic and geometric dimensionless parameters with the discharge coefficient. This project is to study the effect on the hydraulic coefficients which have been made in a rectangular flume with two gate opening of 3 cm and 4 cm, for each opening of gate and sill 3 runs of discharges are carried out and five different gate cases (vertical and inclined vertically) by angle (45)° with and opposite flow direction with sharp lower lip under the three cases of different height of humps 7.5 cm, 10.0 cm & 11.5cm and one case without sill. Different cases of sluice gates are taken in consideration to study the effects on coefficient of discharge,coefficient of velocity & coefficient of contraction by three different humps of different heights are installed under the sluice gates. The opening between the humps and sluice gate is kept 3 cm and 4 cm for every case,three runs of discharge are carried out in each opening. Total of about 120 cases of run of discharge are done in this experimental project. |
