Abstract
The anastomosis glass models are designed and fabricated to investigate the effect of the anastomotic angles (30° to 90° for both forward and backward flow) on the intimal hyperplasia formation. A test rig is designed and built to perform Particle Image Velocimetry (PIV) measurement on the anastomosis models with three Reynolds numbers of 100, 169 and 250. The initial results indicated that there are two low velocity regions, one of them is located at the outer wall of the graft near the joint and the other is located at one diameter down from the joint along the inner wall of the graft. It is found that these low velocity regions are dependent on the Reynolds number and anastomotic angles.
