The objective of this project is to develop a novel method to model fluid-structure interactions and turbulence in cardiovascular systems. The cardiovascular system is essential in providing nutrient and waste transport throughout the body. Because blood vessels and red blood cells are flexible, they are subjected to large deformations with significant effects on physiological functions such as blood distribution and oxygen release. Fluid-structure interactions are critical for understanding the intricacies of such systems but it is still a challenge to model these systems realistically using numerical methods. Expected outcomes of the project include better simulations of three-dimensional fluid-structure interactions and improved understanding of the behaviours of biological systems.Read moreRead less
