Human red blood cell behavior under homogeneous extensional flow in a hyperbolic-shaped microchannel.
It is well known that certain pathological conditions result in a decrease of red blood cells (RBCs) deformability and subsequently can significantly alter the blood flow in microcirculation, which may block capillaries and cause ischemia in the tissues. Microfluidic systems able to obtain reliable quantitative measurements of RBC deformability hold the key to understand and diagnose RBC relate...
متن کاملExtensional flow of blood analog solutions in microfluidic devices.
In this study, we show the importance of extensional rheology, in addition to the shear rheology, in the choice of blood analog solutions intended to be used in vitro for mimicking the microcirculatory system. For this purpose, we compare the flow of a Newtonian fluid and two well-established viscoelastic blood analog polymer solutions through microfluidic channels containing both hyperbolic an...
متن کاملFlow-dependent rheological properties of blood in capillaries.
Velocity-dependent flow of human red blood cells in capillaries with inside diameters of 4 to 8 micron is described theoretically. Cells are assumed to flow in single file, with axisymmetric shapes. Plasma flow in the gaps between cells and vessel walls is described by lubrication theory. The model takes into account the elastic properties of red cell membrane, including its responses to shear ...
متن کاملComment on "Two touching spherical drops in uniaxial extensional flow: analytic solution to the creeping flow problem".
From an analysis of tangent spherical drops in straining flow, Baldessari and Leal conclude that the drop-scale internal circulation, driven by the ambient flow, has a negligible influence on the drainage of the thin liquid film between drops under small-deformation conditions [F. Baldessari, L.G. Leal, J. Colloid Interface Sci. 289 (2005) 262]. However, their conclusion is incorrect as explain...
متن کاملFactors That Influence the Extensional Rheological Property of Saliva
The spinnbarkeit of saliva reflects the ability of saliva to adhere to surfaces within the mouth, thereby serving as a protective role and aiding in lubrication. Therefore, alterations in the extensional rheology of saliva may result in the loss in adhesiveness or the ability to bind onto surfaces. Mucin glycoproteins and their structures are known to be important factors for the extensional rh...
