A small scale vertical axis wind turbine with bamboo blades was built at the University of Vermont in 2014. Prior to 2016, the eﬃciency of the wind turbine was not fully quantiﬁed. Thus, it was desirable to estimate the eﬃciency using computational ﬂuid dynamic models. Thus, a SolidWorks ﬁle of the geometry was created and imported into SimScale, a cloud based CFD software, for anal ysis. Steady-state, quasi 2D simulations of the geometry were simulated with a constant unidirectional wind ﬂow to mimic wind tunnel testing conditions. Simultaneously, a UVM Senior Design team was completing a physical wind tunnel test of the bamboo wind turbine. From the simulations the VAWT was found to have a range of eﬃciencies from 0-0.55% at TSR’s of 0.06-0.11, while from the wind tunnel test the eﬃciencies were in the 0-0.13% range for TSR’s of 0-0.125. Though the simulations calculate a slightly higher eﬃciency of the wind turbine than physically obtained data, they provide a good estimate. Because the wind turbine’s eﬃciency is < 1%, future work will be done with CFD to test altered geometries for the bamboo VAWT to improve its’ performance.
