Laminar Flow in Finitely Wide Rectangular Channels
Experimental investigations in rectangular channels with width-to-depth ratios ranging from 2.74:1 to 100:1 confirm the Boussinesq solution of Poisson's equation for two-dimensional flow. A side-wall function, FBY, is defined as the ratio of the average velocity in a finitely wide channel to that in an infinitely wide channel. Introduction of FBY into the equations for the friction factor and Reynolds number allows comparison of experimental data which have been corrected to what would occur in an infinitely wide channel. The use of the side-wall function is invalid for flows in which the Reynolds number is greater than 800.
