Abstract

We simulated cement fluid in rotational flows of a rheometer. A commercial software COMSOL Multiphysics was used to describe the non-Newtonian behaviors of the cement fluid using a single phase yield stress model. We investigated the effects of the stirrer of the rheometer and the fluid properties (yield stress and plastic viscosity) on both the flow pattern and the total torque required at given rotational speeds. The efficient geometry of the stirrer at given fluid properties is discussed.
