چکیده
|
The work reported in this research presents numerical investigations on the effect of cut-off inclination angle on exit gradient and uplift pressure head under hydraulic structure and determines the optimum location and angle of inclination of cut-off. this problem is solved using the finite element method by using (ansys 11.0). it is concluded that using downstream cut-off inclined towards the downstream side with ө less than 120° is beneficial in increasing the safety factor against the piping phenomenon. the results are evaluated graphically in non-dimensional form.
