A numerical solution of laminar developing flow in eccentric annular ducts
Abstract
Laminar incompressible flow in straight ducts of eccentric annular cross section is analyzed. Numerical methods are used to solve an approximate hydrodynamic model, which was developed from the bipolar coordinate representation of the Navier-Stokes equations. Solutions obtained for the proposed model compare favorably with those of two alternative models and with published solutions for the concentric annulus and the circular tube. Results are presented for five different geometries.
