Abstract
Hydraulic studies of pressure distribution around vertical lift gates
Highlights
Introduction degree and percents of opening gate of [10, 30, 50, 70], Bottom outlet gates plays an important role in hydraulic structures like dams, that task to transmit water, sedimentation discharge and adjusting dam reservoir
One of the common studying methods of researchers is based on hydraulic models
Sagar (1977) showed hydrodynamic coefficient of downpull force based on the basic results of laboratory and 80% were taken account into consideration
Summary
Introduction degree and percents of opening gate of [10, 30, 50, 70], Bottom outlet gates plays an important role in hydraulic structures like dams, that task to transmit water, sedimentation discharge and adjusting dam reservoir. The comparison of pressure distribution in upstream of gate shows in opening 10%, changing of pressure coefficient in 60 degree is softer than 30 degree. Statistical analysis on results of measurement showed that changing angle factor plays an important role on value of pressure coefficient (P-Po)/ Po over on vertical range in behind gate G3.
