Abstract
The present work aims to analyze and compare the fluid dynamic effects on permanent and pulsatile flows, through flexible and rigid tubes with equal internal diameter and different thicknesses in flexible ducts. In addition, also relate the influence of these geometric variants with regard to the flow conditions. To enable these analyses, a mold for making the flexible tubes, as well as the rigid tube model, was designed with the aid of Fusion 360 software (Autodesk, São Rafael, California, USA) and manufactured, through 3D printing. With the aid of a test workbench, permanent flows were simulated, at various pump loads, as well as a pulsatile flow analogous to a physiological pulse. Therefore, it is concluded that the results related to pressure and flow in the pulsatile regime are higher in the rigid tube, when compared to the flexible tubes, due to its non-deformable characteristic. However, in the steady state it was found that the average flow and pressure did not show significant differences. Finally, the similarity between the applied pulsatile flow and the human physiological flow was also observed.
