Jets in cross-flow as wind barrier: Best performing cases and protection mechanism

The use of multiple jets in a cross-flow as wind barriers was proven in a previous study [Franco et al. (2022)]. This study continues the analysis by expanding the wind tunnel tests on twin jets in cross-flow configurations, providing a more detailed description of the leeward flow field of the jets and explaining the mechanism responsible for the good performance of the wind barrier. Hot-wire anemometer measurements were performed on a 324-node grid for 24 combinations of velocity ratios and distances between the jets. This study focuses on two cases characterized by their good performance as wind barriers.
