Normalized mean velocity and Reynolds shear stress profiles across inclination angles plotted in the PIV spatial window. Data is taken between the 8th and 9th rows in the solar farm where a convergence study demonstrated fully developed flow. Flow is from left to right. Red lines indicate the boundary between positive and negative values.Black lines represent the locations of the physical panels, which obstruct the view of the camera in the corners of the measurement window (obstruction shown as white) and prevent data from being taken. Results shown here were taken at nominal wind speed and power input values of 3.9 ms−1 and 450 Wm−2.
