Numerical Simulation Of Immiscible Liquid Liquid Flows In Pipe And Inclined Channel PDF Download

Finally, interfacial behaviors of multi-layer liquid-liquid flow of non-Newtonian and Newtonian fluids in an inclined channel are investigated. The lighter fluid is replaced by a shear thinning, non-Newtonian fluid. A proper empirical model for viscosity constitutive equation is employed for describing the non-Newtonian behavior of the fluid to allow for numerical computation. A comparative study is conducted with suitable range of flow parameters using non-Newtonian fluid as the lighter fluid occupying the upper layer of channel. The thickness of the PEG layer increases as the degree of shear thinning increases. This effect is observed only with gravity induced wavy interface. Shear induced wavy interface does not manifest any effect of shear thinning of the oil for the range of degree of shear thinning effects considered in this study.
