In collaboration with experts from the Czech Technical University in Prague and the Jan Evangelista Purkyně University in Ústí nad Labem, we have developed a new design for a Kaplan propeller turbine that stands out for its wide operating speed range and high efficiency.
Advances in permanent magnet generators (PMG) and frequency converters enable new designs for axial turbines with fixed blades. Thanks to CFD numerical modeling, the blade shape can be optimized to outperform the classic Kaplan turbine.
Simple mechanical construction
- na adjusting mechanism of runner blades
- simple hydraulic profile – cylindrical runner chamber
- low investment and operational costs
Double regulated turbine – guide vanes and opertion speed
- wide regulation range
- soft start and stop
- high cavitation resistance
The Kaplan turbine has fixed blades, eliminating the need for hydraulic control. Blade optimization using an iterative algorithm enables an efficient design with high efficiency and cavitation resistance. The turbine features lower rotational speeds, longer blades that are fish-friendly, and low noise levels, making it suitable even for urban areas. It is designed for a head of 1.5–15 m, a flow rate of 0.5–10 m³/s, and a power output of 10–400 kW.
CFD numerical modeling helps optimize flow, identify losses, and adjust turbine geometry. The resulting design is always tailored to the specific conditions at the given site.
