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.
