Abstract :
The effect of towing tank walls on the performance of a vertical axis turbine has been investigated. A discrete vortex method combined with a panel method has been used to calculate the power coefficient of the turbine running in a towing tank. Higher power coefficients are obtained for the turbine when it is running in towing tank, in comparison to the case for a turbine running in an open free stream. The amount of increase in power coefficient depends on the proximity of the wall to the turbine; the closer the walls are to the turbine, a higher power coefficient is calculated for the turbine.
