First, internal flow fields of blade-turbine generation units are investigated by computational fluid dynamics simulation software. The principal objectives of this part are to determine the relation between the flow and pressure distribution function associated with different types of blade-turbine generation units. On the other hand, the numerical results are analyzed provide new insights into the resistance, lift and torque caused by the blade. Changes from moment are used to design different types of blade-turbine generation units. Two blade-turbine generation units are proposed in the present research. The results show the plan A swing in between 0 to 8 degrees and plan B swing in between 0 to 16 degrees. It is found the plan B provides more power generation efficiency than the plan A.
