Understanding Fluid Dynamics in Pulsatile Pump Systems: How We Simulate Real Blood Flow

Why does the pressure on your pump screen differ from what you measure inside your vascular model? This article explains how pressure changes as fluid moves through tubing, enters larger vessels, and interacts with compliant model walls. Learn why a higher pump setting may be needed to simulate realistic physiological conditions — and how understanding basic fluid dynamics can improve the accuracy of your simulation setup.
