I think that's it, but i also think that a reduction in the diameter of the "nozzles" would be better. Having a nozzle the same size as the "pimple" may not be as efficient.
The reduction of the nozzles would , like bb2k said, implicate a large headloss due to the restrictions. However, having a considerable number of those just might compensate.
