(408a) Transport of LDL and HDL In Blood Vessels

In the paper, ?Pulsatile Flow in a Coronary Artery Using Multiphase Kinetic Theory?, J. Huang, R. W. Lyczkowski, and D. Gidaspow, Journal of Biomechanics, 42 (2009), 743-754, have already shown that the standard multiphase flow kinetic theory model predicts the depletion of red blood cells in the vicinity of the right coronary artery walls, the Fahraeus-Lindqvist effect. D. Gidaspow and J. Hiang have also shown that in a straight tube the model predicts the blood viscosity and the migration of the red blood cells away from the walls in agreement with measurements reported in the literature. We are now applying an extension of the model, including rotation, to describe the transport of LDL and HDL in blood vessels. The diffusion coefficient of particles, such as LDL and HDL, in blood flow is known to be dependent on shear rate and red blood concentration. We explain this dependence using our multiphase kinetic theory model..
