Abstract

Computational fluid-structure interaction (FSI) is a technique that can analyze the flow filed with the deformable channel. The methodology is an effective technique to reveal the blood flow around aortic valve with large deformation. On the other hand, the validation of the solution technique is required. In this study, the objective is developing a flow visualization system for aortic valve model with circulation circuit to validate the computational FSI technique. The aortic valve model has opening and closing function as a valve, and is fabricated from transparent silicone for visualization. The circulation circuit simulates pulsating flow and physiological pressure in a living body. The flow visualization system can measure three components of the flow velocity around the aortic valve model under the pulsating flow.
