6 FAQs about [Photovoltaic bracket wind tunnel test model]
What is a boundary layer wind tunnel test?
Boundary layer wind tunnel tests were performed to determine wind loads over ground mounted photovoltaic modules, considering two situations: stand-alone and forming an array of panels.
Can Rans be used to measure wind load on PV panels?
This study investigated the aerodynamic structure surrounding the roof-mounted PV array and the net mean Cp on PV panels by means of the RANS approach, and mainly analyzing the mean wind loads of panels. The simulated results of downstream panels deviate from the wind tunnel tests apparently due to the limitation of RANS.
Why do the simulated results of downstream PV panels deviate from wind tunnel tests?
