Lattice‐Boltzmann simulation of sago (Metroxylon sagu) starch solutions in porous media

Abstract: From rheological experiments in gelatinized sago starch solution already reported in the literature and a Lattice-Boltzmann simulation, we provide some insight into the understanding of the non-Newtonian fluid dynamics of sago-starch-type solutions in porous media. In this paper, permeability and wall shear stress in arbitrarily generated and randomly generated porous media are predicted in the range of the modified Darcy's law. Additional results on flow paths, velocity, shear-stress tensor, and pressure fiel… Show more

“…The macroscopic variables can be calculated in a direct way from the values of the distribution function as υ τ = − . One of the contributions of the method presented in this work involves a modification of the LBGK presented by Aharonov and Rothman [17], N. Rakotomalala [18], E. Boek [16], and S. P. Sullivan [19], for non-Newtonian fluids (Ostwald-de-Waele), which consists in proposing the relaxation time τ contained in Equation 7, as a function of the apparent viscosity which, in turn, involves the rheological parameters n y k so that [20] ( )…”
