Abstract:
In this experiment, two plastic, saccular aneurysm models were designed, built, and tested. These models more accurately represent aneurysm physiology in the body than those used in Bioengineering Laboratory IV, experiment 4. These models depict aneurysms at different stages of growth in the same vessel. Critical flow rates at the onset of turbulence were determined for two aneurysm models using dye streamlines. Furthermore, critical Reynolds numbers were determined from the critical flow rates for aneurysm models with 6.0 cm and 10.0 cm diameters. The average Reynold’s numbers were found to be 2675 + 436 and 2813 + 358, respectively.
