A two-dimensional flow which is formed by the interaction of the two asymmetric turbulent curved wall jets developed along a circular cylinder is investigated experimentally.
Detachment point of the merged wall jet after the collision of the two opposing wall jets is observed to be strongly dependent on momentum ratio of the two wall jets. However, the relationship between the momentum ratio and the detachment point location is not linear, contrary to the linear relationship of the plane wall jet case.
The wall jet developed along the cylindrical surface (before collision) has the velocity profile of Gaussian distribution as in the case of the single curved wall jet. The growth rate and turbulent intensity of the interacting wall jets are larger than those of the single curved wall jet.
Velocity and turbulent intensity profiles of the merged jet formed after the collision of the two curved wall jets are very similar to those of the conventional plane jet. The spreading rate of the merged jet does not change with momentum ratio, which 1.5 times larger than that of conventional plane jet.
