Abstract: Experiments were conducted in a recirculating water channel in the fluid mechanics laboratory at the National University of Singapore, to identify a scaling parameter for elliptic jet in crossflow (EJICF). Three jet assemblies, which included two elliptic jets of aspect ratios two and three, and one circular jet, all with the same exit area, were used, It was found that within the curves in the same aspect ratio, having different velocity ratio can significantly alter the characteristics of the jet trajectories. This suggests that the increased curvature of the leading-edge vortex loops coupled with the increase in their circulation, plays a decisive role in the jet trajectories. It was also observed that jet exit geometry also plays an important role in determining the resultant jet trajectories.
