dc.description.abstractThis thesis is about estimation of trap efficiency of desilting basin using numerical model program named as SSIIM. SSIIM is acronym for Sediment Simulation in Intakes with Multiblock Option. It is developed by Dr. Nils Reider B. Olsen, Professor at NTNU, Norway and complete software is freely available over net with user manual. The program is a stepping stone in the field of Computational Fluid Dynamics (CFD). Study is based on desilting basin of Tala Hydropower Project (6X170 MW), an Indo Bhutan Joint venture. A physical model study of the same was done in Central Water Power Research Station (CWPRS), Pune, India,. Here this physical model and prototype both has been simulated, but with more emphasis over first one. Three dimensional flow and sediment calculation is evaluated over three dimensional grid using Power Law Scheme (POW) with no heeding towards Second order upwind scheme (SOU). The results are analysed, compared with physical model study and discussed. All the input data i.e. grid co-ordinates and different parameters used are appended in two files named koordina and control, using these program can be run. Number of different options were tried, but only few important has been discussed. Simulation result is found in harmony with physical model result. As real time data of sediment was not available for prototype, a relationship curve between particle size in prototype and model, as per CWPRS report, is used to get input sediment particle size for prototype.nb_NO
