Modelling rheology of isothermal flow of carboxymethyl-cellulose-alginate suspension in a horizontal conduit

Abstract : The rheology of isothermal flow of Carboxymethylcellulose (CMC) solution at 0.5 % mass concentration and, loaded with spherical alginate particles was modeled and analysed. A carrier fluid flow model of solid-liquid pseudoplastic Non-Newtonian suspension in a horizontal pipe governed by constitutive power law of Ostwald Wan der Waal was found not applicable to the range of experimental shearing rates of the flow regime of CMC alginate suspension. Therefore, a new model based on the effect of dynamic viscosity on concentration of the spherical particles in Newtonian flow regimes in relation to Brownian activated motion and hydrodynamics was developed to account for zero shear viscosity and resolve other physical limitations. Upon validation, the dynamic viscosity model fitted the experimental data of the shearing rates
