摘要

This paper explores the design parameters that affect the performance of horizontal-axis water turbines (HAWTs), particularly those conforming to blade element momentum theory. The torque of the turbine is obtained at various rotational speeds by the computational fluid dynamics (CFD) method. This model has been proved to be validated by comparing the simulation results with two sets of experimental data. After the validation, the effects of blade radius, blade number and free stream velocity on the turbine performance are studied. It is shown that the output power of the turbine is approximately proportional to the square of the blade radius when the other parameters are kept constant. Similarly, the output power is approximately proportional to the cube inflow current velocity. 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.
