Studies on jet-in-crossflow have been extensively conducted in the last century. In our paper, we present the results obtained from the measurements of four jets-in-crossflow model developed at a wind tunnel testing facility. The interaction between four jets in a row and a boundary layer crossflow was visualized using a propylene glycol-based fog, and hot-wire anemometer measurements were conducted for quantitative analysis. Vertical profiles of the mean wind speed, relative wind speed, and turbulence intensity are presented for distances of 3.37 and 6.84 diameters from the central plane of the row. Such analysis was also performed for distances between the jets of 1.5, 2, and 3 diameters and velocity ratios of 1.6, 2, and 3.5. A comparison with the literature showed the model performance is comparable to currently reported wind barriers.
