HYDRAULIC AND MIXING CHARACTERISTICS OF SUCTION MANIFOLDS.

摘要

Experimental data were obtained on the external hydraulic characteristics and mixing characteristics of suction manifolds to be used in feasibility and design studies of using such devices for predilution in sewer outfalls. Dilution rates and head loss characteristics are given for six single circular side-port manifolds,for multiport manifolds incorporating the same side ports,and for annular ports with and without axial symmetry. Density differentials have relatively little effect on the dilution-head loss characteristics of the configurations tested. Comparison of the two geometries tested shows that the annular-port manifold possesses hydraulic advantages over single circular side-port manifolds. Limitations of operating ranges of the manifolds in sewer outfall applications are delineated. (WRSIC abstract)
