Pipe flow with radial inflow: Experimental and modeling work

In this paper results are presented fr-ora experiments in which the pressure loss in single-phase pipe flow is studied when radial inflow occurs. Experiments have been carried out with pipes which have different perforation geometries so as to be able to investigate the effect of perforation geometry on the pressure loss. Darn analysis of these experiments, as well as analysis of experiments carried out by other groups, yields a pressure loss model which accurately describes pressure losses in single-phase pipe flow with radial inflow through perforations in the pipe wall. The experimental data is subsequently risen to establish a numerical value of a parameter which is used in a model description. This lends to the formulation of an effective friction factor for pipe flow with radial inflow.
