Key Points
- To determine how a corpuscle-free marginal zone and central unsheared laminae affect apparent fluid viscosity across varying tube radii.
- Analyzed theoretical fluid dynamics in cylindrical tubes featuring a cell-free marginal zone and a central core of unsheared laminae of constant dimensions.
- Demonstrated that narrowing tube radius elevates rather than diminishes apparent viscosity when the marginal layer and central unsheared laminae maintain fixed dimensions independent of vessel diameter.
- Identified that the presence of finite-thickness central laminae counteracts the typical reduction in apparent viscosity usually observed in smaller tubes.

OOutcomeApparent viscosity
The presence of unsheared laminae in the central zone increases apparent viscosity as tube radius decreases.
