Numerical Studies of Aerodynamic Performance of Gapped Flat Plates at High Angle of Attack

Abstract:

In order to study the influence of gap to wind loads on the solar panel, aerodynamic performance of normal flat plate was simulated by various turbulence models with high Reynolds numbers. Time averaged mean drag coefficients and Strouhal numbers were analyzed and compared with other researchers' simulated and experimental results. The flow characteristics of 2D gapped flat plates with different gap sizes at high angle of attack were simulated based on Reynolds stress equation model. Time averaged mean pressure coefficients and Strouhal numbers of gapped flat plates with different gap sizes were compared. The corresponding influences of gap sizes to the pressure coefficients of gapped flat plates were obtained. The simulated results provide theoretical support for the engineering design of the solar panels.
