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-...

Quantitative modelling of the rheology non-Newtonian fluids requires significant empirical input due to very complex behaviour bulk fluid as a result particle-scale physics fluids. The existing models are mainly limited certain dynamics conditions such shear rate, stress, etc. Adopting Doolittle's free volume theory approach, we have proposed an equation describe relative volume-dependent visco...

Magnetorheological (MR) materials and shear thickening fluids are both smart material and their combination could offer both MR and ST effects. This study looks at the properties and behaviour of magnetorheological shear thickening fluid (MRSTF) in particular whilst applied as a semi-active energy absorber. A device with two forms of varying vibration control has been created and measured. The ...

We study optimal control problems of systems describing the flow of incompressible shear-thickening fluids. We prove existence of solutions and derive necessary optimality conditions under precise restrictions on the optimal control.

The flow of a non-Newtonian, power-law fluid, directed normally to long, two-dimensional horizontal bodies, is considered in the present note. It is found that for low Reynolds numbers (Re ≤ 0.1) and a low power-law index (shear-thinning fluids) the drag coefficient always obeys the relationship cD = A/Re, whereas at a high power-law index (shear-thickening fluids) the drag coefficient tends to...

The application of intelligent materials in drilling fluids has greatly reduced the investment human resources and effectively made up for shortcomings traditional fluids, such as insufficient directivity, poor adaptive ability difficult monitoring. Therefore, research is a valuable direction future oil gas industry. In this study, temperature-sensitive modified bentonite NIPAM-B developed by P...
