水上光伏基座水体交换对影响因素的响应
Response of Water Mass Exchange in Floating Photovoltaic Modules to Influencing Factors
摘要
Abstract
The planar laser induced fluorescence(PLIF)method was employed to investigate the mass exchange characteristics of water in floating photovoltaic modules.The impact of temperature difference,ambient flow velocity,and perforation rate were observed.The experimental results indicate that the dimensionless concentration of the original warm water in the module decreases exponentially over time,with the retention duration determined by the combined effects of temperature difference,flow velocity,and the perforation rate.Under small temperature differences,flow velocity has a significant impact on the mass exchange,while an increased perforation rate is more effective under large temperature differences.In addition to providing direct diluting effects,the water flow from the punching area was observed to enhance the large-scale circulations in the turbulent layer at the bottom of the base module,resulting in a significant improvement in overall mass exchange efficiency.关键词
