0619 3分割型CPVのスリット幅が空力特性に及ぼす効果

抄録

This paper deals with the aerodynamic characteristics of the concentrated photovoltaic system (i.e. CPV) of three-divided-panel type. A preceding experimental study indicates that the moment around the shaft supporting the panel decreases when the acceptance surface of the panel faces downstream ('downstream case'). To investigate the mechanism, we conducted measurements on the aerodynamic forces in a wind tunnel. It is found that as the slit width increases, the moment gradually decreases to small values when the acceptance surface faces downstream. This reduction probably comes from uniformity of the pressure distribution on the rear surface for the downstream case.
