• Reliable drag model identification: shear-thinning, -thickening, Newtonian fluids. Investigation of temporal phenomena (periodic shape fluctuations). Higher indexes (K, n) mean more sphericity and slow movement in linear path. Model extension for predicting small bubble rise low-viscosity liquids. A study the effects fluid type (shear-thinning, Newtonian, shear-thickening) periodic fluctuatio...

in the current study, the immersed boundary – non-newtonian lattice boltzmann method is developed for simulation of forces act on a particle and also for computation of the particle velocity in vicinity of non-newtonian fluids. in this research, the effect of extra force due to accelerated mass is also considered in non-newtonian particle motion equations. two applied problems of power-law non-...

We investigate the influence of the fluid constitutive model on the outcome of shape optimization tasks, motivated by optimal design problems in biomedical engineering. Our computations are based on the Navier-Stokes equations generalized to non-Newtonian fluid, with the CarreauYasuda model employed to account for the shear-thinning behavior of blood. The generalized Newtonian treatment exhibit...


 Rayleigh-Bénard's convection is a classic problem of heat transfer. Since the 1900s, studies for Newtonian fluids have been widely developed in this field and phenomena well understood. On other hand, complexity non-Newtonian behavior makes number much lower. Among behavior, shear-thinning fluid are even rarer. This work focuses on numerical study natural shear thinning, Rayleigh-Bénard ...
