✦ Synopsis

this work, the dynamic of particles in a non-Newtonian (Bingham) fluid is considered, developing a mathematical model (one nonlinear, free boundary, first-order PDE) for the sedimentation of particles in a cylindrical, axis symmetric flow. We proved existence and uniqueness (locally in some circumstances) of the solutions, and we tested numerically the fitting of the model with the real physical problem.

## Abstract **Summary:** Non‐Newtonian fluid behavior has significant influence on quantities in chemical engineering like power input, mixing time, heat transfer etc. In the laminar flow region, the concept of effective viscosity by Metzner and Otto is well established. In the transition region be
