Longitudinal laminar flow in asymmetrical finite bundles of rods

Theoretical analysis is presented on the asymmetrical effects, i.e. peripheral displacement of rods or unequal rod diameters, on longitudinal laminar flow in a finite bundle of rods. Solution is by the method of superposition. Numerical results are obtained for shear stress and velocity distributions when only one rod is displaced in a seven rod cluster of equal-diameter rods.
