The influence of gas blowing on spray drag of surface

Applied hydromechanics, Vol. 6 (78) ¹ 2, (2004) p.60-64
Results of an experimental investigation of air supply influence through the perforated surface to its drag in a spray flow are expounded in the article. Ability of significant reduction of a spray drag of a plate in a spray flow with the help of a cross rows gas distribution is shown and the correspondent amount estimation of air feed parameters is done. An advantage of the ribbed surface in the realization of the spray drag reduction mechanism has been found. A maximal effect of the spray drag reduction for the ribbed surface is 300% in comparison to the used for a spray blow off impulse.
