Open Source Mesh Generation and CFD Simulations for Francis Turbine

Hydro power can be recognised as a relatively mature technology of all renewable energies.Eciency around 90 % are commonly observed in Francis turbines. Since hydro power is relatively cheaper among other power sources, it is used as base power in energy systems. Additionally hydro-power plants are often operated at design conditions,which may lead to cavitation. Accordingly design improvements for improving the eciency of the turbine at design conditions are of great interest to designers.Computational fuid dynamics is used often for this analysis for predicting fuid ows as per modi ed design.
