Research on Wind Shape Coefficient of Photovoltaic Panel Based on CFD
The wind shape coefficient is an important parameter to calculate the wind load on solar photovoltaic panels.Based on the fluid mechanics analysis platform Fluent,the wind pressure distribution law,wind speed vector and wind load shape coefficient of photovoltaic panels under different wind direction angles and installation inclination angles are studied by Reynolds time average method,and the simulation results are compared with national codes.The calculation results show that the changes of wind direction angle and installation inclination angle have significant effects on the wind load.The decreasing direction of positive pressure and negative pressure on the surface of photovoltaic panel is consistent with the direction of air flow;There is a large pressure difference at the windward edge of the upper and lower surfaces of the panel,which is easy to cause wind-induced damage to the photovoltaic panel;According to the CFD numerical simulation results and comparative analysis with national codes,the recommended values of wind load shape coefficient of photovoltaic panels under different installation inclination angles and different wind directions are put forward.The research results can provide a certain reference basis for the wind-resistant design of solar photovoltaic modules.
