Mathematical Model for Air Flow from Perforated Circular Ducts with Annular Corrugations
ABSTRACT A mathematical model has been developed for the prediction of air flow and pressures in perforated corrugated ducts. Experimental tests have demonstrated the validity of this model for ducts with annular corruga-tions. Additional refinements in the model are needed to produce accurate predictions for ducts with helical cor-rugations. Dimensional analysis techniques were used to generalize the results. These results may be used in the design or analysis of air distribution systems for agricultural storages.
