Approximation of the oscillatory blood flow using the Carreau viscosity model

Unsteady solute dispersion in non-Newtonian fluid flow in a tube with wall absorption

“…The Carreau-Yasuda fluid with four sets of parameter values, Carreau fluid with four sets of parameter values, Newtonian fluid for n = 1 and Casson fluid with four values of yield stress of the fluid[14] are incorporated in this study, and the comparison of these fluids on K 2 has been made with the effect of reaction rate at the tube wall.Figure 3aexplains that the differences of magnitude of K 2 occur between these Newtonian and non-Newtonian fluids in the steady flow situation. The behaviour of K 2 for all Carreau fluid models(Carreau fluid 1, 2, 3 and 4)is close to the Newtonian behaviour with the chosen set of parameters at low shear rate[28,29]. However, the nature of the Carreau fluid depends on…”

“…The that Carreau-Yasuda, Carreau, Newtonian and Casson fluids exhibit significant variations of −K 1 with varying values of β in the steady flow situation. The behaviour of −K 1 as β varies with the chosen set of parameter values for Carreau fluids (Carreau fluid 1, 2, 3 and 4) and Newtonian fluid is not significantly different even in magnitude, as both these fluid models exhibit similarity at low shear rate [28,29]. The deviation of Carreau-Yasuda models (C-Y fluid 1, 2, 3 and 4) from the Newtonian fluid behaviour is seen for low shear rates, and the significant difference in Casson models (Casson fluid 1, 2, 3 and 4) is also observed from the other non-Newtonian and Newtonian fluid behaviour.…”

Magnetorheological elastomer peristaltic pump capable of flow and viscosity control

“…The viscosity of fluids extremely affects the physical, chemical, and biological properties of non-Newtonian fluid (Kutev et al, 2015; Oka et al, 2005). Previous studies adjust the viscosity pattern with obvious change in the net pumped volume.…”

“…MREs where magnetic particles are embedded into an elastomer matrix are widely applied in vibration absorbers (Sun et al, 2015), smart vibration isolation systems (Oliveira et al, 2017; Khoo and Liu, 2001; Song et al, 2016), soft microrobots (Diller et al, 2014; Hu et al, 2018; Lum et al, 2016; Sitti, 2018; Xu et al, 2019), and so on. This characteristic is also utilized in sensitive liquid conveying, especially drugs and biofluids (Fuhrer et al, 2013; Kutev et al, 2015). The magnetorheological elastomer peristaltic pump (MRE-PP) without any moving parts is first presented by Fuhrer, and related scheduling policies of electromagnets are also investigated to restrain backflow (Fuhrer et al, 2013).…”

“…Besides, the bidirectional conveying of fluids cannot be achieved in these devices. The precise net pumped volume is also not obtained easily, although it is necessary in many engineering fields (Barnoon and Toghraie, 2018; Kutev et al, 2015; Ma et al, 2017; Oka et al, 2005; Taitel and Dukler, 1976; Tao et al, 2016; Vasilyeva, 2017). In the previous study, we presented a 2D smart MRE-PP to convey water and blood bidirectionally (Wu et al, 2019a) and a three-dimensional (3D) MRE-PP with an analogic moisture loss process (Wu et al, 2019b).…”
