چکیده
The paper narrates a study of a numerical model taken into consideration to explore the overall hydraulic performance of Constructed wetland located at NUST H-۱۲ Campus, Islamabad. The governing equations of flow in wetland ponds and the transport particle were solved using COMSOL Multiphysics ۵.۰. In this study, the simulation of the model is done to find the dead spaces and short-circuiting in the wetland along with providing remedial measures to reduce the dead spaces. The comparison of two turbulent models i.e. K-ω and K-ε were also made to depict the velocity of wetland and the particle tracer study was also conducted to find the behavior of wetland. The model was simulated with experimental data and the results revealed that ۱۵% to ۲۰% area of wetland is experiencing short-circuiting. Alternative wetland designs were suggested for the same flow condition. The K-ω model was considered to be more suitable due to the limitation of K-ε model.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
