Pump-Turbine Reservoir CFD Simulations
This project was performed in 2010 for an accurate study of flow patterns in a pump-turbine reservoir. During the operation, water from downstream is pumped and delivered to the reservoir. At the second step the water in the reservoir flows through the turbine. Due to geometry design for this reservoir, in this project a comprehensive CFD simulation to study the effect of pumping and flow patterns in reservoir on turbine hydraulic efficiency was performed. Using numerical simulation the effect of various parameters on plant hydraulic efficiency was specified.

1.7 Km Overflow Design of Rogun Dam in Tajikistan Using CFD Simulations
This project was performed in 2012 with the aim of Rogun dam overflow design. Several approaches for an optimum design were evaluated. 1.7 Km overflow hydraulic design must be combined with the geological studies. Soft rock eases the excavation but enough strength for radial gate installation is an important factor that must be considered. Overflow diameter reduction can save expenses in excavation, on the contrary smaller tunnel results in higher velocity flow and requires steel lining that can increase the expenses. Using comprehensive CFD simulations, the optimization of different factors such as excavation expenses, steel lining expenses and rock density was achieved and proper overflow was designed.

CFD Simulation of Water Flow in Tana River in Kenia
This project was executed in 2009 to study the effect of river sedimentation growth on water delivery to hydraulic power plant. In this river water flow can be controlled with the radial gates. Using CFD simulation the effect of various parameters such as water depth and flow controlling strategies was investigated on power plant efficiency.

Two Phase CFD Simulation of Karun 3, Gotvand and Siah Bishe Surge Tank
This project was performed in 2010 with the aim of simulation and optimization of Karun 3, Gotvand and Siah Bishe surge tanks. Surge tanks are used in hydro power to damp the pressure fluctuations. Based on numerical simulations for Gotvand surge tank, in some water levels because of the improper design the destructive wave can even be formed with a time delay. Using two phase CFD simulations, the modifications were exerted and new design was produced.

Comprehensive Supercavitation Study for Cavitator Design Knowledge Development Using CFD Simulations
This project was performed in 2006 to provide a deep insight into supercavitation phenomenon in Arya Alborz Company. Supercavitation phenomenon takes place behind an object under the water with the reduction of static pressure to water vapor absolute pressure. To study this phenomenon, different surfaces such as plane, spherical and wedge were simulated and drag coefficients at various cavitation numbers were validated with water tunnel tests. Based on investigation in this project the cavitator design knowledge was produced in Arya Alborz Company.

Two Phase Flow Numerical Simulation of Sedimentation Growth in the Sea
This project was performed in 2005 to study and simulate the sedimentation growth on the pier foundations. According to the flow regime, water velocity, topography and other parameters, sediments formation can take place close to the pier foundations. Due to the difficulty and high costs for dredging of the seabed, the effect of various parameters using comprehensive CFD simulations in a real case was studied and good insight of sedimentation prediction was developed in Arya Alborz Company.
