The Manifold Problem

Abstract

Abstract This paper deals with the general problem of manifolds supplying fluids to a set of parallel pipes or ducts, or discharging through numerous openings distributed along the manifold length. Examples are the familiar “pipe burner” for gaseous fuels; the manifold of the “radiant-fire” type of gas burner; headers or manifolds for certain types of multitube air heaters; the distributing flues above and below the checkers of open-hearth furnaces and of glass tanks; furnace combustion chambers containing heat ports; distributing pipes in water-filtering systems; and many others. The very specialized problem of the gasoline-engine manifold is not considered here.
