Reactor Module for Vascular Flow and Shear Stress Simulation

The patent creates physical copies of vascular bifurcation models using 3D printing technology. Instead of relying solely on theoretical CFD simulations, the invention fabricates accurate physical replicas of blood vessels with varying diameters, bifurcation angles, and branch patterns. These physical models are then placed in a controlled flow chamber where fluid dynamics can be directly observed and measured, significantly improving simulation accuracy while maintaining manageable system complexity through standardized modular components.

The patent replaces the purely computational CFD mechanical system with a hybrid experimental setup. Physical vascular models are subjected to controlled fluid flow in a laboratory setting, allowing direct measurement of hemodynamic parameters. This substitution enables researchers to validate and refine CFD models with empirical data, thereby improving reliability while using the physical models to simplify complex computational requirements.

The patent designs a universal flow chamber system with standardized interfaces and modular components that can accommodate various vascular models with different diameters, bifurcation angles, and branch patterns. The adjustable flow rate mechanism and interchangeable vascular models allow the same experimental apparatus to simulate multiple biological environments efficiently, eliminating the need for separate computational setups for each scenario and significantly improving productivity.

The patent implements a dynamic flow control system that can adjust flow rates, pulse frequencies, and pressure gradients in real-time to mimic different physiological conditions. This dynamic capability allows researchers to efficiently simulate various biological environments by simply changing operational parameters rather than redesigning the entire experimental setup, thereby enhancing both efficiency and adaptability.
