“…Results from Stokes Second Problem were higher but within the same order of magnitude as those of the simulations. This result is consistent with a study by Khan and colleagues [19]. They compared analytic solutions of an oscillating fluid between two sidewalls to that without side walls.…”

To mimic in vivo vibration of vocal fold cells, we studied the controllability and range of frequency, acceleration, duration, and shear stress in a new bioreactor attachment. The custom multiwell disc appliance fits into a commercially built rheometer, together termed a torsional rheometer bioreactor (TRB). Previous attachments to the TRB were capable of 50-100 Hz vibrations at relatively high strains but were limited to single-sample experiments. The TRB-multiwell disc system accommodates 20 samples in partially fluid-filled wells in an aseptic environment delivering three different acceleration conditions to different samples simultaneously. Frequency and amplitude used to calculate acceleration along with duration and shear stress were controllable and quantifiable using a combination of built-in rheometer sensors, manufacturer software, and smooth particle hydrodynamics (SPH) simulations. Computed shear stresses at the well bottom using SPH in two and three dimensions were verified with analytical approximations. Results demonstrate capabilities of the TRB-multiwell disc system that, when combined with computational modeling, provide quantifiable vibration parameters covering frequencies 0.01-250 Hz, accelerations of 0.02-300 m/s 2 , and shear stresses of 0.01-1.4 Pa.

“…Nadeem et al [13] presented the peristaltic flow of a Jeffrey fluid with variable viscosity in an asymmetric channel. Some unsteady flows of a Jeffrey fluid between two side walls over a plane wall has been reported by Khan et al [14], whereas Hayat et al [15] discussed the boundary layer flow of a Jeffrey fluid with convective boundary conditions. Thermal radiation effect on the mixed convection stagnationpoint flow in a Jeffery fluid and the effects of an endoscope and magnetic field on the peristalsis involving Jeffrey fluid are also presented by Hayat et al [16,17].…”

The steady two dimensional convective boundary layer flow of micropolar Jeffrey fluid past a permeable stretching sheet is studied in this paper. The governing boundary layer equation in the form of partial differential equations are transformed into nonlinear coupled ordinary differential equations and solved numerically using an implicit finite-difference scheme known as Keller-box method. The effects of Prandtl number, Deborah number, and material parameter with the boundary condition for microrotation, n = 0 (strong concentration of microelements) on the velocity, microrotation, temperature profiles as well as the skin friction and heat transfer coefficients are presented and discussed. An excellent agreement is observed between the present and earlier published results for some special cases. The results revealed that, the effect of Deborah number and stretching parameter are increased the heat transfer coefficient while the opposite trend is observed for the effects of material and velocity slip parameters. It was also observed that, the values of skin friction increased with the increment on the values of all studied parameters.

“…Also, examined velocity and shear-type driving forces for Couette flow, transient Poiseuille, and wind-driven flow in parallel plates and a finite domain, respectively, with the impact of the Jeffrey fluid model. Khan et al 14 studied the flow under constant applied stress induced by an oscillating and an accelerating plate. Turkyilmazoglu 15 studied the impression of thermal radiation with MHD over a rotating disk, which was immersed in a viscous fluid.…”

The problem of Jeffrey’s nanofluid for a modification of Homann’s exterior potential flow in the stagnation region is modeled over a cylindrical disk. The characteristic of electrically conducting nanofluid flow with a time-independent free stream is noted as well. Due to this, a new family of asymmetric flows is created, which mainly depends on the viscoelastic parameter [Formula: see text] magnetic parameter [Formula: see text] and the stress-to strain rate ratio, i.e., [Formula: see text] By deploying Buongiorno’s model and Rosseland’s approximation, the outcomes of the Brownian diffusion, thermophoresis, and solar radiation on the mass and thermal boundary layer are also scrutinized. The conservation laws are remodeled by a similarity transformation, and the governing equations are solved by a builtin program bvp4c in Matlab. Furthermore, a comparison is made between the numerical outcomes and their large- γ asymptotics for wall stresses and displacement thicknesses. It is discovered that due to the impact of Jeffrey’s material parameters and magnetic field, when [Formula: see text] reaches infinity, along the x-axis the two-dimensional displacement thickness and the coefficient of skin friction are closer to their asymptotic values; however, along the y-axis, they exhibit opposite trend. Moreover, the thermal and mass transport is enhanced due to significant contributions of nanofluid conductivity.
