“…With no rotation, the volume fraction distribution is symmetric along the A-A plane. The particles tend to accumulate near the center line, also see Figure 8a; this agrees with the results predicted by the multicomponent model of [79,80]. As increases, the particles tend to migrate in the direction of the angular speed of the inner cylinder; furthermore, we also notice that the high concentration of the solid particles in the narrow gap gradually begins to become more uniform, see Figure 8a as well.…”

Abstract:The effects of various conditions on the fluid flow, particle migration and heat transfer in non-linear fluids encountered in drilling and geothermal applications are studied. We assume that the drilling fluid is a suspension composed of various substances, behaving as a non-linear complex fluid, where the effects of particle volume fraction, shear rate, and temperature on the viscosity and thermal diffusivity are considered. The motion of the particles is described using a concentration flux equation. Two problems are studied: flow in a vertical pipe and flow between two (eccentric) cylinders where the inner cylinder is rotating. We consider effects of earth temperature, the rotational speed of the inner cylinder, and the bulk volume fraction on the flow and heat transfer.

“…Another factor that may limit cell motion near the wall is a phenomenon referred to lift force [20][21][22]. Because of their deformability, the RBCs modify their shape and direction as they enter the higher shear regions of the flow boundary layer.…”

Recently, a dialysis-like filtration device has been devised to remove the red blood cells infected with the malaria parasite from whole blood using magnetic separation techniques. The capturing efficiency of this process depends on many interrelated design variables and constraints such as magnetic pole array pitch, channel height, length and flow rate. In this study, these parameters are varied in several common optimization algorithms, so as to minimize the channel length while maximizing the capturing efficiency. The equations of motion are solved numerically to predict the trajectories of the infected cells within an idealized rectangular micro-channel incorporating periodic high gradient magnetic poles. The channel length of the optimized design is obtained, together with the associated capturing efficiency. The optimization of the channel geometry and flow rate improves the efficiency of the device.

“…(5) and (6), we can see that constitutive relations are needed for the stress tensors and for the interaction force. In the next section we provide a summary of the mixture theory approach suggested by Massoudi et al [11] and also indicate the modifications of the drag and the lift coefficients that we will use in the current study.…”

“…Plasma behaves like a viscous fluid and for the range of shear rates studied there is no significant deviation from linearity [20,11]. The normal range of plasma viscosity is 1.1-1.3 cP at 37°C and independent of age and gender.…”

a b s t r a c tUsing the Theory of Interacting Continua (Mixture Theory), blood is modeled as a twocomponent mixture, namely, plasma and red blood cells (RBCs). The plasma is assumed to behave as a Newtonian fluid and the RBCs are modeled as a suspension of rigid spherical particles with a viscosity dependent on the shear-rate and the hematocrit. The drag and lift forces are implemented through RBC-plasma interaction forces. We solve the governing equations using the OpenFOAM, an open source CFD code for two phase flow simulations. The two-phase simulations predict RBC depletion in the corner of a sudden expansion channel. The RBC depletion length is found to increase with decreasing the flow rate and the hematocrit. There is a qualitatively good agreement between the simulation results and the experimental data.Published by Elsevier B.V.
