The current experimental investigation focuses on analyzing the breakup mechanisms and droplet features of a liquid jet introduced into a low-speed cross air flow. The main aim of this study is to investigate the spray behavior of water when exposed to a uniform cross flow of air at very low velocities. A shadow sizing system is employed to collect comprehensive data for analyzing the interactions between liquid jets and cross-flowing air. Three different nozzles were used to examine the distribution, penetration, and breakup characteristics of water jets in an air cross flow. It is worth highlighting that the Weber number in this experiment was maintained at a very low level. Both the jet Weber number (1.3<Wej<119) and the gas Weber number (0<Weg<1), along with the momentum flux ratio (2<q<14400), are crucial dimensionless parameters significantly affecting various droplet properties such as size, velocity, shape, and breakup behavior. This study investigates the structural features, trajectory of the jet, and duration of breakup near the nozzle. Subsequently, the experimental results are tabulated for future numerical and analytical studies.
