BIOMECHANICS WITH
PIV AND CFD

Fluid dynamics which is one of fundamental theories of mechanical engineering can be extensively utilized in engineering processes for biological applications. Based on our strengths of mechanical technology, we are studying on bionic application such as medical diagnostics and nature-inspired design.


Medical diagnostics of cerebrovascular stroke

It is known that mechanism of stroke occurrence in cerebrovascular is affected by shear stress distribution on the wall. In order to find out more accurate stroke incidence mechanisms, we visualize blood flow characteristics using PIV measurement system to verify the relation of the wall shear stress distribution and stroke incident mechanism in the cerebral vessels. As sharing the information with medical team, the final goal is to propose a treatment that considers the patient’s blood flow characteristics.

In addition to the hemodynamics of middle cerebral artery, we are interested in blood flows of internal carotid artery (ICA). In the ICA, recirculating flow is induced due to carotid sinus and the recirculation is thought to play a role on plaque growth. Thus, the hemodynamics related to the ICA shapes are also carefully analyzed through PIV experiments and CFD simulations.
