| Περίληψη | The prediction of the terminal velocity of solid spheres falling in non-Newtonian shear thinning stagnant liquids is required in many industrial applications. Various correlations have been proposed but an accurate and comprehensive equation covering the whole range of Reynolds numbers is not yet available. Furthermore, there is scarcity of much needed experimental data to aid in the derivation of the optimal correlation. Many investigators opt for using correlations derived for Newtonian liquids. However, there is a great variety of such correlations and not much is known about the optimal one or about the differences among them. The scope of this work was to propose an equation for predicting the terminal velocity of solid spheres falling in non-Newtonian shear thinning stagnant liquids. The equation is firstly chosen by comparing the various proposed correlations using three indicators. It is then compared to experimental data taken using solid spheres falling through water solutions of Carboxylmethylcellulose of various concentrations and Newtonian fluids. The equation proposed compares favorably both to the experimental data presented and to experimental data reported by other investigators | en |
