This paper reports an experimental investigation on the zone between two parallel planar jets in a crossflow, termed as the interaction zone. The experiment was conducted using 2D PIV measurement, which involves a test matrix designed for a parametric study. Based on both mean and instantaneous results, effects of different parameters, i.e. front jet velocity, space between the two jets, and crossflow flow velocity, on the interaction zone were analysed. The two coupled recirculation structures, size, velocity field, and turbulence characteristics of the interaction zone are discussed. In addition, the large-scale vortices inside the interaction zone were recognised using Γ1 value. How these different parameters affect the evolution of these vortices was also studied
