Savonius vertical axis wind turbines have simple structures, can self-start in environments with low speed and strong turbulence intensity, be installed at costs. Therefore, installation is possible urban centers speeds, which may contribute to the construction of a decentralized power system. are operated by drag force, blades moving same direction as flow current providing thrust force those ...

Many recent studies show that the performance of Savonius turbines can be considerably increased by using wind deflectors. Axisymmetric deflectors are particularly interesting; they concentrate flow in all directions. This study aims to aerodynamically optimize truncated cone deflector shape through transient 3D CFD simulations sliding mesh techniques. To reduce size and thus simulation time, s...

Recently, many countries are looking for alternative energy sources that renewable and environmentally friendly, one of which is wind energy, with Indonesia's potential 9 GW relatively low speeds geographical position, it necessary to develop turbine technology suitable characters in Indonesia. In this research, an omnidirectional director model (ODGV) developed around the savonius aims improve...
