Abstract

GreenValve (integrating a runner into a ball valve) is a highly promising solution for harvesting excess water energy from the pipe to power the electrical equipment in the pipe network. In order to better match the actual operation of the GreenValve and to realise the simulation of the non-stationary operation process of the GreenValve, a modified passive model is proposed in this paper. The model is based on the idea of incoming flow induced rotor rotation and on a modification of the 6-DOF model that takes into account the added mass of the fluid. Based on the model, the energy harvesting characteristics and fluid regulation characteristics of the GreenValve with a modified Savonius runner with different number of blades and hollow ratios are investigated. Numerical results show that at an inlet flow rate of 15.7 × 103 m3/s, with the increase in the number of blades, the movement of the runner tends to be smooth, and the power and efficiency of the GreenValve gradually increases, up to 245 W of power and 13.6% of efficiency; the increase in the hollow ratio from 0.25 to 0.33 improves the overall performance of the GreenValve.
