(A) Steady-state velocity field u_z(r) in the experimental flow channel, the magnitude is indicated with the colorbar in (m/s). The red lines indicate streamlines and the cut planes show the velocity magnitude. The dimensions are as indicated in Figure 1C and the channel has a total width of 3 mm and height of 3.65 mm. An aqueous fluid with viscosity η= 0.78mPa s and density ρ= 997.8 kg/m³ flows through the device at a steady flow rate of Q₀= 125 μL/min. (B) Shear stress on the cells τ_{zr, cells} in the center of the microfluidic device as a function of the azimuthal angle ϕ around the fiber. Here, ϕ = 0 corresponds to the top of the fiber.
