The low wind speed causes the power produced by the wind turbines become smaller than expected. To overcome the conditions with the same rotor diameter, one of the way to increase the wind speed by using a diffuser. This research was conducted by simulation method of Autodesk CFD 2019 software aimed to find out the increase of wind speed inside the entrance diffuser in model k-ε and SST k-ω. …
Flanged diffuser is a type of diffuser. The purpose of this diffuser is to increase the wind speed that come through the wind turbine using the turbulence principal. The difference of this diffuser is at the flange or the flat ring at the outlet of this diffuser. This flange is mean to gives bigger turbulence increase. The purpose of this research are to find the increamennt wind effect and the…
