| Abstract: | Based on theory of momentum conservation, relations between spray performance of centrifugal spray nozzle and configuration parameters of the nozzle have been analized in this paper,and some theoretical formula are established. Predicted mean spray angles of the nozzles are in accordance with the experiment data certain extent.Because the effect of the fluid viscosity is ignored, predicted nozzle discharge coefficients are slightly lower then the experiment data. The theoretical formula in this paper can be used as the calculation fundamentals for spray performance of common centrifugal spray nozzles. |
