Description
Description
This project simulates unsteady pulsatile blood flow in an artery bifurcation simplified model by ANSYS Fluent software.
The fluid domain geometry is designed in the Design Modeler, and the computational grid is generated using Ansys Meshing. The mesh type is unstructured, and the element number is 168367.
The inlet’s blood mass flow rate and outlet are equal to 0.001570178 and 0.00078576 kg/s, respectively. The blood pressure in the inlet is equal to 250 Pa, approximately 1.87515 mmHg. It is worth mentioning that blood pressure in large arteries in the human body varies between 120 and 80 mmHg.
Pulsatile Blood Flow Methodology
The pulsatile nature of blood flow is simulated using a User-Defined Function (UDF), which changes the inlet velocity according to flow time as a sinus function.
Pulsatile Blood Flow Conclusion
The simulation solver in this project is unsteady, and the results shown here are in the flow time equal to 0.162s, representing the peak value for the velocity function. One of the most exciting results of this project is the determination of prone regions of artery wall rupture.
As seen from the pressure contour at a flow time equal to 0.16s, the blood pressure on the bifurcation tip, where two flow streams diverge from each other, reaches high values equal to 125Pa, which is half the pressure of the fluid at the inlet.
Another interesting conclusion to make from the results is the regions that are most likely to form stenosis. In literature, areas with low Wall Shear Stress (WSS) are most likely to form stenosis. As shown in the figure illustrating the WSS values, the most likely region for stenosis formation is the tip of bifurcation.

How does the simulation account for the bifurcation in the artery?
MR CFD Support –
The geometry of the model accurately represents an arterial bifurcation. The flow physics at the bifurcation are captured by solving the Navier-Stokes equations, which govern fluid motion.
Mrs. Abigayle Jerde V –
The use of UDF to simulate pulsatile flow is interesting. How specifically was the sinus function implemented, and how did you ensure its accuracy for modeling blood flow?
MR CFD Support –
In the simulation of pulsatile blood flow, the UDF (User-Defined Function) was written in the C programming language and used to define the sinusoidal variation of velocity at the inlet according to a time-based function. To ensure accuracy, the UDF would have parameters based on physiological data, such as the frequency and amplitude of blood pulsation, matching the cardiac cycle. This is validated by comparing simulation results with experimental data or established benchmarks in hemodynamics literature.
Evalyn Schimmel –

How does the simulation handle the pulsatile nature of the blood flow?

The simulation handles pulsatile flow by incorporating time-dependent boundary conditions. These conditions mimic the natural rhythmic contraction and relaxation of the heart, which is essential for accurately simulating blood flow in arteries.

Ellsworth Little –
The simulation’s outcomes are impressive! The investigation of areas at risk of artery wall rupture and stenosis formation provides valuable insights. Could you please provide more details on how you determine the regions prone to these conditions?
MR CFD Support –
Certainly! The regions prone to artery wall rupture are identified by analyzing the pressure contours within the artery model. The segments that demonstrate significantly high pressure, such as the bifurcation tip in our simulation, are considered at higher risk. For stenosis formation, areas with low Wall Shear Stress (WSS) values are considered susceptible to stenosis. This is based on clinical knowledge that low WSS is associated with the deposition of atherosclerotic plaque. By examining the calculated WSS distribution in our results, we can spot those regions that have extraordinarily low WSS and label them as potential stenosis sites.

The methodology indicates the use of a UDF for pulsatile flow. Could the same results be achieved using built-in Fluent functions, or is a UDF essential for accurate simulation in this case?
MR CFD Support –
A UDF is vital in this specific simulation to accurately mimic the physiological pulsatile nature of blood flow. While there are built-in functions in ANSYS Fluent for imposing flow variations, they may not provide the same level of precision or customization in representing the complex time-dependent waveforms evident in actual blood circulation.
