Improving the effectiveness of a photovoltaic water pumping system by spraying water over the front of photovoltaic cells

Abdolzadeh, M.; Ameri, M. - In: Renewable Energy 34 (2009) 1, pp. 91-96

performed by spraying water over the photovoltaic cells. The results are compared with traditional systems. Experimental results … show that the cells power is increased due to spraying water over the photovoltaic cells. This can significantly increase … the system and subsystem efficiency and the pump flow rate when operating under different heads. Measurements of the short …

Development of automated chopper gun trajectory planning for spray forming

Chen, Heping; Xi, Ning; Kamran Masood, Syed; Chen, Yifan; … - In: Industrial Robot: An International Journal 31 (2004) 3, pp. 297-307

Automated chopper gun trajectory planning (CGTP) for spray forming is highly desirable for today's automotive manufacturing. Generating chopper gun trajectories for free‐form surfaces to satisfy material distribution requirements is still highly challenging due to the complexity of the...
