CFD Optimized Fixed Blade Kaplan Runner — Small Flow Micro Hydro Solution The CFD Optimized Fixed Blade Kaplan Runner is specifically engineered for small flow, low head micro hydropower plants (100 kW – 1,000 kW). Unlike standard fixed-pitch runners designed solely for design-point operation, this runner leverages advanced Computational Fluid Dynamics (CFD) simulation to extend the efficient operating range into lower flow conditions, maximizing annual power generation
