This work explores the performance improvement of a Savonius Hydro Turbine (SHT) installed inside a 4-inch pipeline by examining the combined effects of the guide-vane angle and central-shaft opening ratio were assessed through Computational Fluid Dynamics simulations supported by experimental measurements. Five turbine configurations (M5-1 to M5-5) were analyzed with the SST-enhanced k–ω turbulence formulation under guide-vane angles of 0°, 25°, 30°, and 35°. The results revealed that both parameters significantly influence the flow field and turbine efficiency. The central-shaft opening reduces reverse flow and torque reversal acting on the retreating blade, whereas the guide vane channels the incoming stream toward the forward-moving blade. Among all configurations, the M5-3 turbine (30 % opening, 35° guide vane) exhibited the most favorable performance, yielding maximum power coefficient (Cp,max) value of 0.3969 (simulation) and 0.3778 (experiment) at Tip Speed Ratio (TSR) close to 0.59. These represent 233 % and 257 % improvements, respectively, compared with the case without a guide vane (M5-3, 0° guide vane). Compared with the solid-shaft turbine (M5-1, 35° guide vane), Cp increased by 48 % (simulation) and 55 % (experiment). The deviation between simulated and experimental Cp ranged from 5.06 % to 12.38 %, decreasing with increasing guide-vane angle, validating the CFD predictions. The combination of a 30 % central-shaft opening and a 35° guide-vane angle produced the most efficient flow interaction, showing strong potential for low-head, in-pipe hydropower recovery in industrial and municipal pipeline systems.
