Abstract: The onset of viscous fingering in the presence of a viscosity profile is investigated theoretically for two immiscible fluids undergoing a time-dependent injection. Here, we show that the presence of a positive viscosity gradient at… read more here.

Abstract: In processes such as foam injection molding, due to the strong dependence of melt viscosity on gas content, the overall viscosity of a polymer melt will increase once the air phase (i.e., the bubbles) is… read more here.
