Numerical simulation can be used to predict fluids flow through abrupt expansion, and hence to help us to optimize the expansion design. The behavior of magnetic fluids (MFs) flowing through an abrupt expansion is investigated without the application of magnetic field. The Herschel-Bulkley (H-B) model was employed as the constitutive equations. By changing the parameters in the H-B model, different flow patterns of MFs flowing through an expansion were obtained. Vortex length (Lv) of the recirculation zone was analyzed.
