Simulation of Blood Flow in Coronary Artery

The heart is covered with arteries that also known as the coronary artery which in blood vessel the oxygenated blood from the lungs is being transferred to the heart. The blood flow in human arterial system can be considered as a fluid dynamics problem. Simulation of blood flow in the coronary artery will provide a better understanding of the physiology of human body. The simulation also gives the doctors to predict the behaviour of the coronary artery blood flow to avoid any unwanted problems. The main objective of the project was to demonstrate and stimulate the blood flow in the coronary artery by using a Computational Fluid Dynamic (CFD) modelling approach. The simulation used software ANSYS Fluent 18.2 which provide us with the details of the behaviour of the blood flow. The steps of achieving the simulation will be shown in the report and also the parameters used for the simulation such as density of blood, viscosity of blood and the shear stress on the wall of the vessel. The project aims to see the effect of coronary artery bypass graft (CABG) with length 9mm and 10.5 mm towards the right coronary artery with plaque blocked within the artery simulation. The project will be stimulated the changes of velocity of the blood flow in the RCA.
