On the Development of a Wind Energy-Based Efficient Irrigation System

Results of an extensive wind tunnel test program aimed at development of a Savonius rotor-based irrigation system are summarized. The system uses an optimum configuration of the turbine and a novel coil-pump. Results suggest the system to be quite effective, with the turbine speed and tube diameter of the pump influencing the flow-rate while the number of turn of the coil-pump governing the head attained. Thus appropriate design of the system can provide the desired performance. Simplicity of construction, self-starting character, low speed operation, ease of maintenance and economy make the system quite attractive.
