 Modelling the integrated output of wind-driven roto-dynamic pumpsSathyajith Mathew and K.p Pandey Renewable Energy, 2003, vol. 28, issue 7, 1143-1155 Abstract: Roto-dynamic pumps offer better match with wind rotors for low lift-high discharge water pumping applications. Tremendous potential for such systems does exist in many developing countries like India. In the present study, a mathematical model is proposed for estimating the performance of wind-driven roto-dynamic pumps at various operating conditions. In contrast with the earlier attempts in this direction, an integrated approach incorporating the characteristics of the rotor, pump and the wind regime is envisaged for formulating the model. The model is validated using the field performance data from a 5 m, five-bladed experimental rotor coupled with a low speed centrifugal pump. Performance of the system at fluctuating conditions of wind regimes is estimated and compared with that of a system with reciprocating pump. Wind driven roto-dynamic pumps are found to offer distinctly better performance than the conventional system with reciprocating pumps. Effects of the specific speed and specific diameter of the pump on the gear ratio and optimum pump size are also discussed. A low specific speed roto-dynamic pump with reasonable specific diameter is found to be suitable for coupling with wind rotors for water pumping application.
