Ferromagnetic Fluid Flow through a Circular Channel

Abstract

Experimental results on a channel flow of a finely dispersed suspension of magnetites in water are presented over a wide range of Reynolds numbers and mean shear rates. It is shown that the fluid behaves as a non-Newtonian fluid and the magnetic field causes the non -Newtonian behavior to increase. Another contribution of the field to the flow is an increase of resistance in laminar flow and a decrease of resistance in turbulent flow. Experimental formulas for pipe friction coefficient and transition Reynolds number are presented.
