Blood flow dynamics and vascular fluid mechanics.

The article focuses on using MATLAB simulations to model blood flow dynamics and vascular fluid mechanics by solving Navier–Stokes equations to analyze velocity distribution, pressure gradients, and the effects of vessel geometry and blood viscosity. It demonstrates that under normal physiological conditions, blood flow in vessels is predominantly laminar with a parabolic velocity profile, while increases in viscosity or changes in vessel diameter can significantly alter flow resistance and pressure distribution. The study employs Reynolds number calculations to distinguish laminar, transitional, and turbulent flow regimes, highlighting critical velocity thresholds relevant to cardiovascular health. Through two-dimensional and three-dimensional visualizations, the research provides insights into hemodynamic behavior that have implications for diagnosing vascular disorders and optimizing clinical treatments. This computational framework offers a valuable tool for advancing biomedical research and the design of therapeutic interventions related to cardiovascular function.
