“…method and the software "Matlab". The flow behavior is discussed in the momentum, thermal and concentration boundary layer for Weissenberg number We (due to Carreau fluid parameter), buoyancy parameter 𝜆 (due to temperature difference), buoyancy ratio parameter Nr (due to concentration difference), Schmidt number Sc (due to concentration boundary layer), Eckert number Ec (due to viscous dissipation term) and Prandtl number Pr (due to thermal boundary layer) through Figures 2-9, and the values of the remaining parameters are chosen from the [37]. 4 that the growing values of the buoyancy ratio parameter due to the concentration difference causes a reduction in the friction between the molecules that make the fluid thin, and the flow along the disk becomes fast in the velocity boundary layer region.…”

The unsteady flow of a Carreau fluid over a coated disk under the simultaneous effects of a thermal and concentration field with buoyancy forces is reported. The time-dependent diffusive stream of a Carreau fluid over a conducting coated disk is carried out with energy loss. The time-dependent partial differential equations are first converted into a scheme of ordinary differential equations by the appropriate transformations and are then solved by shooting method. Significant results for speed, hotness and concentration profiles are revealed and deliberated by the graphical outcomes. The numerical values of skin friction suggest that the viscoelastic parameter of the Carreau fluid causes a reduction in the skin friction coefficient due to the coated surface, but the Nusselt and Sherwood numbers increase with the rise of the viscoelastic parameter of the Carreau fluid because of the coated surface. The present model is useful in the field of mechanical engineering to design a tesla turbine for the flow of viscous fluid.

“…In order to describe the temperature dependence of the shear viscosity, the Arrhenius equation and the WLF equation [5] are commonly used to describe the effect of temperature above the glass transition temperature. Rehman et al [6] studied the mathematical formula of Cross model. Hina et al [7] reported the related results of using the Cross model to simulate the shear thinning fluid.…”

Viscous models such as Bird-Carreau, Cross, modified Cross, Carreau-Yasuda and Power are often used in commercial software. In order to get the most suitable model, a series of rheological tests were carried out in this study, and a model fitting method based on least square approach was proposed. Combined with the WLF equation related to temperature, these five viscous models were fitted by the fitting method proposed in this paper. The calculated results of the fitted models are compared with the experimental data. The results show that, of the investigated five models, the Carreau-Yasuda and Cross type models can better describe the rheological characteristics of ABS, the Bird-Carreau model is the second, and the Power model is the poorest one. The fitted models are in good agreement with that by Polymat. Some models such as Cross and Power models fitted by the proposed method are even better than that by Polymat.
