这副图是国外的一个朋友设计的利用太阳能转换为热能再传递给水转化为机械能最后产生电能的过程。

必须要平放?如果不能总是正对太阳,效率会大大降低。而如果要整个系统跟随太阳,可能会得不偿失。

design use because of their ability to produce an acceptable estimate of the gross machine performance. As blade designs have evolved, however, it has become clear that these simple schemes have some specific deficiencies which limit the useful information which can be generated by them. In particular, they often neglect unsteady aerodynamic effects and, just as importantly, the influence of rotation on flow development. Attempts have been made to address these two problems and, in this respect, much progress has been made in understanding and predicting the unsteady aerodynamic environment in which wind turbines operate. The primary focus of the work at Glasgow has been to develop a sophisticated aerodynamic prediction tool (Prescribed Wake Model) that addresses the full complexity of wind turbine flows. In addition, attention has been given as to how simpler preliminary design level codes can be improved.
Wind turbines operate at all times in an unsteady aerodynamic environment. Factors such as atmospheric turbulence, wind shear, skewed flow, and the influence of the turbine tower on the blades, etc., all have significant effects on turbine blade inflow conditions. In addition to these factors, the disparity between the timescales associated with changes in wind direction and the yawing speed of a typical turbine inevitably results in the turbine operating almost continuously in some degree of yawed flow. Under yawed conditions the blades experience cyclic variations in incidence which can, if severe
