The numerical results showed the effect of blade number on both power output and starting capability.
In model development, profile type, blade number, Schmitz coefficient, end loss, profile type loss, and blade number loss were taken as input variables, while the TSR and power factor were taken as output variables.
Concerning the blade number, an increase beyond a certain number will cause a drop-off in power production; for the turbine configuration which is discussed, the optimal blade number is three.
Although both the power and torque coefficient were improved significantly by the optimisation of the blade number, there was only a slight change when the blade number was greater than twenty.
After the validation, the effects of blade radius, blade number and free stream velocity on the turbine performance are studied.
The solid hold-up was affected by the rotation rate, flow rate, blade number, blade angles and material flow properties.
Blade number and blade discharge angle should be conveniently determined when splitter blades are used on the impellers.
Design parameters, like blade number, blade outlet angle and impeller outlet diameter, affect pump performance and energy consumption.
The relative variance was primarily influenced by the flow rate, rotation rate, blade number and material flow properties.
Hence, the inter-particle mixing was enhanced with the increase of the rotation rate and blade number.
The position, blade number, and circumferential length are then investigated when the turbine is mounted on a building.
