Abstract
In this paper, turbulent flow causing erosion in Tunnel 1 of Tarbela Dam using Reynolds Stress Model considering the effect of sediment particles is discussed. Velocity, pressure and erosion rate results are presented for three different water heads in the reservoir i.e., considering summer, winter and average seasons both for one-way and two-way/full coupling. Erosion rate is concluded the maximum at main bend and outlets at high head at full coupling. Numerical results are compared with the experimental erosion results for the scale down model of almost similar geometrical components. In addition, maximum loss of mass at T section in the loop with time is concluded.
