摘要：
Loss coefficients for laminar flow of an incompressible Newtonian and non-Newtonian fluids flowing in an eccentric annulus are calculated by modelling an eccentric annulus as a slit of variable height. While the loss coefficients for a power-law fluid are smaller than those for a Newtonian one, the reverse is true for a Bingham fluid. In the limiting case of a concentric annulus, the results are found to be in good agreement with those reported in the literature.
