Abstract
A comparison of predicted and measured performance of the bi-directional Islay Wells air turbine is presented. Reasonable agreement was evident for pressure, converted power and efficiency, at lower flowrates. For higher flowrates larger discrepancies were evident due to limitations in the theory, inaccuracies in experimental measurement and flow separation at the Islay turbine. It was concluded that improvement could be achieved through streamlining of the flow through the turbine, in order to defer turbine stall at the higher flowrates and to also improve flowrate measurement. Improvements are necessary in the measurement of flowrate and power conversion, and in the prediction technique.
