Hydro turbine models refer to scaled-down, transparent models of the water flow components of the actual turbine, including the full-transparent spiral casing and tailrace, designed to mimic the real turbine's hydraulic performance. These models clearly demonstrate, through observation and testing of the scaled-down turbine, the cavitation performance of the turbine's runner, among other characteristics.

During the operation of the turbine model, guide vanes must be adjusted in accordance with the load, while the runner rotates and adjusts the blade angle to maintain a good coordination with the guide vanes, which is referred to as "dual regulation." This ensures that the turbine maintains a high efficiency over a wide range of output.
Tilted Flow Turbine Model: The transparent PMMA casing, inclined in arrangement, is fixed on the seat ring. The twelve seat ring pillars are inclined at 35° to the horizontal line. The inclined guide vane mechanism with a 45° angle consists of twenty-four guide vanes, a guide vane drive mechanism, the turbine top cover, and the guide vane bottom ring. The guide vanes with a double support structure have symmetrical airfoils varying in height. The guide vane bearings are wooden bushes, lubricated automatically by water passing through. To prevent water leakage, a rubber bowl is fitted on the upper shaft neck. The guide vane drive mechanism is composed of a crank arm, a connecting rod connected to the crank arm with a ball pivot, and a control ring connected to the connecting rod with a ball pivot. The hinge of the control ring is connected to two annular impellers.
The runner blades of the runner-type water turbine model can automatically adjust their angle of placement according to the operating conditions, matching the opening degree of the guide vane. To rotate the blades, the runner body is equipped with pistons, cylinders, piston rods, operating frames, connecting rods, and cranks, etc. The upper part is connected to the main shaft with a pressure oil pipe, while the lower part is fixed with a drain cone. Most of the main shafts are horizontally arranged, with a few being inclined.
Axial flow turbine model, a horizontal shaft turbine model where the water flows primarily along the horizontal axis within the channel. It is mainly suitable for heads of 1 to 25 meters and is a type of low-head, high-flow hydroelectric power station model. Due to the water flowing primarily along the axis without turning, the turbine's water passage capacity and hydraulic efficiency can be enhanced. Particularly suitable for tidal power station models, its features such as bidirectional power generation, bidirectional water pumping, and bidirectional water draining are ideal for comprehensive utilization of low-head hydraulic resources.
Axial flow turbine wheels can be categorized into two types: fixed-paddle and variable-paddle. The main difference lies in the variable-paddle wheel's ability to automatically adjust the blade angle in response to changes in guide vane opening and head, maintaining a good co-relationship with the guide vanes. During the operation of the turbine, the guide vanes must be adjusted according to the load. The wheel, while rotating, adjusts the blade angle to maintain a good co-relationship with the guide vanes, known as "dual regulation." This ensures the turbine maintains high efficiency over a wide range of output. Fixed-paddle wheels, however, cannot adjust the blade angle during operation. When the unit load changes and the guide vane opening is altered, the blade angle cannot be adjusted promptly, leading to water flow impacting the blades. As a result, the turbine's efficiency range is narrow across the entire output spectrum. Despite this, their simple structure makes them still widely used in small and medium-sized power stations.
