Water or oil? Both? It looks like you might have problems with the oil due to the restricted outlet for the air. It is smaller than the inlet and should be larger than the inlet. If you use a spray bar, it should be a fine spray. Almost atomized for best results. That means high pressure and fine nozzle. Can you taxi during these tests?
