Computational fluid dynamic (CFD) simulations of a small wind turbine with a simple frustum diffuser shrouding have been carried out.
The research presented in this paper parameterizes the power augmentation of a small wind turbine (AMPAIR 300) shrouded with a simple frustum diffuser, based on diffuser’s length and area ratio (outlet area/inlet area) using CFD simulations.
As can be seen the maximum Cp of the MWT obtained by CFD simulation is 13.8% achieved in l = 2.3 while in the DAMWT it is 19.5% and in l = 3, which means the performance has 41.3% increased.
Then simulations were done with these RPM and wind speeds.
Conclusion AMPAIR 300 wind turbine shrouded with different frustum diffuser shapes has been studied using CFD simulations.

However, there have been very few reports on prediction accuracy of CFD simulations about wind flow around buildings.
Furthermore, the effect of different calculation conditions (such as size of computational domain, grid resolution, boundary conditions and selection of turbulence model, etc.) on CFD simulations is not understood.
Using numerical CFD simulations have many advantages for optimizing wind tunnel experiments.
