Flow Characteristics of Single Phase Fluid in Multiorifice Distributing Pipe and Collecting Pipe

This paper presented flow models of multiorifice distributing pipe and collecting pipe with variable pitches. By theoretical deducing, their analytical solutions were obtained. Based on it, formulas of the velocity distributing divergence through small hole, flow distribution in axial were obtained. Finally, the pitches distributing functions in continuous and discrete forms in which the flows uniformly distribute and collect were also given. The results provide effective solving methods for the design of distributing and collecting pipe of single phase fluid flow in the power, chemical and mechanical engineering.
