Two different techniques for simulating the performance of a helical Savonius rotor of 1m high and 0.5 diameter with 180o twist angle are compared in this study. Designed to operate at a wind speed range of between 2 to 5 ...

This paper investigates the sensitivity of time step and time increment on the performance of 1800 twist helical Savonius rotor using commercial computational fluid dynamic code based on flow-driven method. The ...
