The Carreau, Casson, and generalized power-law models were superior for solving blood flow at all shear rates compared to power law, Walburn-Scheck, and Herchel-Bulkley models.
Carreau, Casson, and generalized power-law models are superior for simulating blood flow hemodynamics across all shear rates compared to other common models.
Blood flow in the human vascular system is a complex to understand example of fluid dynamics in a closed conduit. Any irregularities in the hemodynamics may lead to lethal cardiovascular disease like heart attack, heart failure and ischemia. Numerical simulation of hemodynamics in the blood vessel can facilitate a thorough understanding of blood flow and its interaction with the adjacent vessel wall. A good simulation approach for blood flow can be helpful in early prediction and diagnosis of the mentioned disease. The simulation outcomes may also provide decision support for surgical planning and medical implants. This study reports an extensive review of various approaches adopted to analyze the influence of blood rheological characteristics in a different class of blood vessels. In particular, emphasis was given on the identification of best possible rheological model to effectively solve the hemodynamics inside different blood vessels. The performance capability of different rheological models was discussed for different classes and conditions of vessels and the best/poor performing models are listed out. The Carreau, Casson and generalized power-law models were appeared to be superior for solving the blood flow at all shear rates. In contrast, power law, Walburn-Scheck and Herchel-Bulkley model lacks behind in the purpose.
Kannojiya et al. (Wed,) conducted a review in Cardiovascular disease. Rheological models (Carreau, Casson, generalized power-law) vs. Other models (power law, Walburn-Scheck, Herchel-Bulkley) was evaluated on Performance capability of different rheological models for solving blood flow. The Carreau, Casson, and generalized power-law models were superior for solving blood flow at all shear rates compared to power law, Walburn-Scheck, and Herchel-Bulkley models.
