 Topic: Water and Sediment Flow Simulations through Reservoirs and Tunnels

Abstract:

Tarbela dam is one of the largest earth filled dams in the world. It is used for water storage and electric power generation. It comprises of six tunnels, three of which are used for power generation and three for irrigation purposes. Sediments inflow in Tarbela reservoir has resulted in reduction in water storage capacity and damage to the tunnels and plant equipment. It is also the backbone of Pakistan (water, food and energy). In this presentation, results of numerical simulations carried out for the very first time to study sediment and cavitation erosion rate through reservoir and tunnels for different seasons (summer, winter and average), for different outflow combinations and sediment delta movement in the reservoir. In addition, studies regarding velocity and pressure profiles vary with and without sediments. Sediment and cavitation erosion with one way and two way coupling at all heads, for different turbulence models (K-ε and RSM) and injection techniques with two way coupling are carried out. More results will be in the presentation.

The above seminar will be delivered by Professor M. Abid who is visiting the School of Design, Engineering & Computing at BU on Monday 10^th and Tuesday 11^th December. His visit to BU is externally funded by the British Council Knowledge Exchange Grants for International Strategic Partnerships in Research and Education. Prof. M. Abid received his PhD degree from University of Strathclyde, Glasgow and presently working as Dean Faculty of Mechanical Engineering, GIK Institute, Pakistan. His research interests are in the areas of Renewable Energy Systems, Structural Mechanics, Welding Mechanics and Computational Fluid Dynamics. During his two day visit he will be meeting several staff to identify opportunities of research collaborations and exchanges, staff/students mobility in education related activities and will be participating in teaching activities within the Design & Engineering Framework at Level C, I and H.
