Title Centerline velocity gradients for plain and flanged local exhaust inlets
Bibliographic information Oct. 1981, Vol.42, No.10, p.739-746. Illus. 8 ref.
Abstract Experimental data obtained recently for high velocity, low volume, exhaust nozzles was compared with findings from the studies of circular, rectangular and narrow slot inlets, conducted by Dalla Valle and Silverman in the 1930s and 1940s and used as the basis for design equations. The application of the existing design equations for circular and rectangular inlets and narrow slots was generally confirmed. Significant variations were noted for flanged and rectangular configurations. The implications of the experimental and analytical methodology are discussed.
