How does perforations enhances mixing in jet flows?

06 June 2016 1 10K Report

if we use perforated tabs instead of solid tabs how will it improves the mixing?

I think it may be for that the jet injection velocity is increased due to the smaller injection slot diameter after changing the perforated tabs. Then the jet penetration height and the turbulent intensity would also be increased due to the increasing of jet injection velocity, which will in turn enhance the mixing process in jet flows.
