Volume of Fluid Model of Open Channel Contraction

Datta, I. / Debnath, K.

Abstract In the present paper, the effect of channel contraction has been studied using FLUENT. Contracted channels having three different contraction ratios (0.77, 0.61, and 0.44) have been investigated. The effect of channel contraction on the vertical profiles of longitudinal mean velocity, turbulence intensity, turbulent kinetic energy (TKE) and turbulent dissipation rate in comparison to the open channel case is explored. The velocity profile of the contracted channel with contraction ratio 0.44 is compared with experimental data obtained from laboratory flume experiment. The mean longitudinal velocity, turbulence intensity, TKE and turbulent dissipation rate increases with the decrease in contraction ratio and vice versa.
