“…A scheme with a Savonius rotor installed in a pipe was reported in [53]. The uniqueness of such a scheme lies in that a semi-circular shield was used to shield half of the rotor, as shown in Figure 16a.…”

Applications of the Savonius rotor have been extended in recent years, necessitating an in-depth investigation on flow characteristics of such a fluid energy converting device. For the wake flow downstream of the Savonius rotor, studies have been reported extensively. Nevertheless, literature specifically devoted to the upstream flow of the Savonius rotor can rarely be found. This review collects and compiles findings from relevant studies to prove the significance of upstream flow patterns to the operation of the Savonius rotor. Then attempts from experimental and numerical aspects to substantiate the important effect of the upstream flow are implemented. Based on practical cases and laboratory works, upstream flow patterns for the Savonius rotor are divided into four types, namely uniform flow, guided flow, rotor wake flow and oscillating flow. Accordingly, conditions under which these upstream flow patterns arise are analyzed respectively. Experimental and numerical results are presented to clarify the influential factors underlying diverse upstream flow patterns. Furthermore, the relationship between the performance of the Savonius and the upstream flow is elucidated, facilitating the development of techniques of controlling the upstream flow. This review provides a systematic reference for the control of the upstream flow for the Savonius rotor, which has the tendency of developing into an independent technical branch.

Fluid flow emerges with high velocity referred as liquid jet. Water Jet having its applications in many fields includes agriculture and power generation and it has been widely utilized. Impact value of the jet is highly important, to generate maximum efficiency in operation. Many factors influence the impact value of jet and it depends on type of vane used such as: Flat, hemispherical, curved etc. The aim of this work is to investigate the impact coefficient of jet for various discharges by comparing theoretical forces as well as forces developed through experiments for different target vanes. A systematic estimation of theoretical forces, experimental forces and its error was done in this experiment. For this purpose, weigh balance, target plates, vanes, recirculation pipes and Rotameter were used. Result of this study indicate: discharge variability influences the impact value and for a particular discharge obtained values are within the limit.
