Correlation of Hemorheology Parameter Hematocrit with Hemodynamic Factors and Arterial Diseases

Appl. Rheol. 20:6 (2010) 64092 (7 pages)

Abstract: Blood rheology and hemodynamics models show positive correlation between hematocrit and hemodynamic factors that has implication to physiological and arterial disease processes. Blood flow is modeled by the Navier-Stokes equation and its non-Newtonian property by the Casson equation. Hematocrit dependent parameters in the Casson equation integrate the hematocrit level in the mathematical model. Then the mathematical model was linearized on a tetrahedral computational grid using the finite volume method. Results show strong correlation between hematocrit and hemodynamic factors. The determined hemodynamic factors and their strong correlation with the hematocrit provide explanation how these factors promote the atherosclerotic process in the right coronary artery at a steady flow and how influence arterial disease process. © 2010 Applied Rheology.
