Title

Investigation on Pressure Variations at Stilling Basin Bed

Pages

  99-112

Abstract

 Stilling basin is one of the energy dissipater structures that are used frequently in downstream of hydraulic structures, such as spillways, sluice gates and chutes. The energy dissipation, due to macro-scale turbulence, makes intensive Pressure Fluctuations so it must be carefully considered when structures are designed. The experiments were carried out in a rectangular flume, 0. 3m by 0. 4m; and Froude Numbers from 3 to 12. The pressure variations data at flume bed and the water level data were recorded by electronic pressure Transducer and by piezometers, respectively. The results showed that the intensity of Pressure Fluctuations in Hydraulic Jump was related to the Froude Number and relative situation from the jump toe. The maximum Pressure Fluctuation intensity coefficient C'pmax varied from 0. 08 to 0. 28 at the distance of 17 to 33 percent of the jump length. The maximum value of C+P was equal to 2 and maximum absolute of coefficient C-P was equal to 1. 2 occurred at X/Lj≤ 0. 4. Longitude distribution of pressure and its fluctuation and critical values in the length of Hydraulic Jump also were obtained.
