This problem simulates arterial occlusion considering blood by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

In this project, a vessel with two branches is modeled. The fluid used in the simulation process is blood, which has a density of 1060 kg/m3 and a viscosity of 0.35 kg/m.s. There is a stenosis in the middle of the vessel. A curvature line function has been used to define and plot the vessel’s stenosis.

This simulation aims to investigate the behavior of the blood passing through this stenosis. The mass flow rate of the blood flow to the artery from both inlet branches is 0.002385 kg/s, and the vessel wall is assumed to be static.

The geometry of this project is designed in the ANSYS design modeler and is meshed in ANSYS meshing. The mesh type is structured, and the element number is 85222.

Arterial Method

For the geometry of the vessel, a curve line function was used to plot the stenosis of the vessel branch. This function represents the sum of the points x and y that make up a curvature line obtained from the relation ‘‘y=0.0002475cos((πx)/0.001)’’.

For example, the curve is assumed to be 30% of the vessel’s congestion; This means that the ratio of the diameter of the vessel in the area with clogging to the diameter of the vessel is 0.7.

Percentage of clogging in the vessel changes to compare the behavior of the fluid in different states. The changes in the percentage of clogged arteries are 30%, 40%, 50%, 60%, 70%, 80% and 90%, respectively.

Arterial Conclusion

After simulation, 2D contours of pressure and velocity, as well as 2D pathlines and vectors, are obtained. The velocity contour indicates that the maximum velocity value occurs exactly at the stenosis point; Because the cross-section of the fluid reaches a minimum.

The pressure contour shows that the pressure of the fluid decreases after passing through the stenosis and its value is less than the pressure at the inlet of the two branches.

Also, the plots of pressure, velocity, and pressure drop according to the percentage of clogged arteries are presented. According to the plots, as the percentage of clogged arteries increases, the pressure drop of blood increases, and the velocity of blood passing through the clogged area also increases. This is because the high percentage of clogging indicates more obstruction of the vessel path.

    Can you explain how to verify that the simulation correctly predicts the physics of blood flow through different levels of arterial occlusion?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Verification in this complex simulation can be conducted by comparing the simulation results with experimental data or established analytical solutions when available. Another method involves conducting a mesh independence study to ensure that further refinement of the mesh does not significantly change the results. Lastly, assessing the quality of the boundary conditions and the input parameters for their physiological relevance is essential for a realistic simulation.

    I’m very interested in the method you used for the vessel stenosis mapping. The curvilinear function is quite fascinating. Could you provide more details on how this function feeds into the simulation setup in layman’s terms?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Certainly! Basically, the curvilinear function is a mathematical representation that we use to mimic the narrowing of the artery, which is known as stenosis. Imagine squishing a part of a pipe, making that part narrower. The function tells the software exactly how to shape that narrow section by giving a list of coordinated points to form that part of the artery. The function changes the width to resemble an actual artery with a blockage. This information lets the software know how blood would flow through this narrowed part, allowing us to analyze how fast it goes and the changes in pressure as it squeezes through the constraint.

    The tutorial mentions variations in stenosis percentage; can you elaborate on how changing the degree of stenosis affects the simulation results?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In the simulation as described, varying the degree of stenosis changes the maximum flow velocity and pressure drop across the stenosed area. An increase in stenosis percentage leads to a higher velocity at the narrowest section due to the reduced cross-sectional area for flow. This also results in a greater pressure drop since the fluid elements lose more energy while accelerating through the stenosis. Therefore, higher degrees of artery clogging result in more pronounced changes in blood dynamics, which is essential for understanding the implications for cardiovascular diseases in clinical applications.

    The presentation of the simulation results was very clear! Could you explain how occlusion percentages affect intervention strategies?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Our simulation results demonstrate how varying degrees of arterial occlusion impact blood flow. As occlusion percentages rise, both pressure drop and blood velocity increase due to more significant obstructions. Clinicians may utilize this crucial data to design effective intervention strategies. Precise quantification of occlusion severity lays the groundwork for determining whether stent placement, angioplasty, or possibly surgical intervention is necessary for restoring adequate blood flow.

    The tutorial mentions changes in percentages of artery clogging to compare fluid behavior. How does this variation affect the computational requirements of the simulation?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      With each increase in the percentage of artery clogging, the complexity of the flow behavior increases, which in turn may require a denser mesh near the stenosis and possibly more computational iterations for the solution to converge. As a result, computational time and resources may increase with higher percentages of occlusion to ensure accurate results for fluid behavior.

      MR CFD Support

      The findings of these simulations are indeed beneficial for the medical field, particularly in vascular surgery and cardiology. They can help in understanding the hemodynamic changes induced by arterial occlusion, which can assist in the design of medical interventions, such as the sizing and placement of stents, or in surgical planning for artery bypass grafting procedures. Furthermore, these simulations help predict the risk of potential complications such as local ischemia or distal embolization, thus aiding in the development of preventive measures and treatment strategies for arterial diseases.

    What exactly is being investigated in this arterial occlusion simulation? Is there a particular clinical scenario or condition it is meant to represent?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In this arterial occlusion simulation, we are mainly investigating how different percentages of arterial stenosis affect the behavior of blood flow through the vessel. This includes looking at changes in velocity and pressure as blood passes through varying degrees of occlusion. These conditions may represent a range of clinical scenarios from mild to severe arterial blockages that might be found in cardiovascular diseases such as atherosclerosis. The goal is to understand the flow characteristics and potential impacts on blood circulation and pressure, which are critical factors in medical diagnosis and treatment planning.
