Power-frequency relationship of wave dynamics in fluid-filled compliant tubes

This study investigates how wave reflection influences pulsatile power in compliant tubes, providing new insights into cardiovascular biofluid dynamics. Using a reduced-order fluid-structure interaction model, we identify distinct frequency-dependent regimes in pressure-flow dynamics, separated by optimum frequencies that minimize pulsatile workload. Our findings underscore wave reflection as a key mechanism for strategically controlling inflow generator workload, informing the optimization of medical devices involving fluid-filled compliant tubes.
