概要 | The experimental data, which can be the object of the comparison with the theory, and in which the data of the drag coefficients of the windmills are contained, are obtained for the 2, 3, 4 and 6 blad...ed windmills. The simple formulas for the calculation of the coefficients of torque, drag and power of windmills are found, and these formulas agree well with the results of the experiments. The distributions of the lift coefficients along the blades are calculated by these formulas at the maximum power states. The performances of the windmills having the circular cylinder outside of them are investigated by the experiments and analyses.続きを見る |
