Text of Abstract
Many complex materials have thixotropic behaviors, displaying time dependent viscous and elastic properties that are a function of microstructure. Some examples of thixotropic materials are aqueous nuclear waste, crude oil, and paints. Another example is blood. Modeling the behavior of these materials allows us to better understand how they can be used effectively in their respective industry. We have characterized human blood using recently collected steady state data and the Bautista-Monero-Puig (BMP) model. First, we analyzed steady state data and compared parameter predictions to physiological parameters, then we simultaneously fit the BMP model to steady state and a transient sawtooth function again using recently collected blood data. Using the best fit BMP parameter values from the steady state-sawtooth fit, we predicted small amplitude oscillatory shear (SAOS), and LAOS. We also demonstrate and compare using fits with step up/step down transient experiments. We characterize blood to develop better models, and evolve strategies to give way to better understanding of blood to facilitate benchmarking blood’s “normal” rheological fingerprint, with a view toward a methodology to diagnose pathologies based on rheological deviations from blood’s baseline mechanical properties. Based on the biochemistry of blood, its fluid mechanics, and rheological properties, pathological blood will have different rheological properties than healthy blood. By modeling healthy blood, we can establish a baseline that will then allow us to characterize and diagnose pathological blood based on its flow behavior, as was seen in the Moreno paper with high cholesterol. We then look for statistically significant relationships between certain model parameters and physiological parameters measured from the blood like cholesterol, sugar, hematocrit, etc.
