In this project, a Lumen Blood Vessel (FSI & Non-Newtonian) has been simulated, and the simulation results have been investigated using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

The three-dimensional geometry of this project has been produced with Spaceclaim software. The length of the computational domain is 164 mm, the height is 262mm, and the width is 5 mm.

The meshing of this project has been done with ANSYS Meshing software, and the total number of elements is 356794.

Also, due to the nature of the present problem, the transient solver has been used.

Lumen Blood Vessel Methodology

In this project, a blood vessel with its wall has been simulated using Ansys Fluent software. Also, the intrinsic FSI module within the Fluent has been enabled, and wall displacement is considered.

We have defined the pulse velocity using UDF for the inlet boundary condition, and for the outlet, the pulse output pressure is defined using UDF.

The blood is modeled as a non-Newtonian fluid using the Carreau model. Moreover, the laminar model is enabled to solve the fluid equations.

Lumen Blood Vessel Conclusion

At the end of the solution process, three-dimensional contours related to wall displacements and von mises stresses are obtained. As can be seen, blood flow inside the vessel exerts stress on the vessel walls.

    I found the case very interesting! Is the Carreau model crucial for the blood flow simulation?

    • Avatar Of Mr Cfd Support

      Yes, indeed, the Carreau model is crucial for accurately simulating blood flow in CFD analysis. This model takes into account the non-Newtonian properties of blood, meaning that the viscosity of the blood changes with different shear rates, which is important for realistic simulation of blood flow dynamics in blood vessels.

    I found the project fascinating, especially how it utilized both the FSI and the non-Newtonian Blood model via Carreau. Could you please provide more details about the pulse velocity and output pressure UDFs and how they influence the accuracy of the simulation compared to constant flow simulations?

      In the simulation of biological flows like blood in a vessel, the use of pulse velocity and output pressure UDFs (User-Defined Functions) is essential for mimicking the pulsatile nature of blood flow due to the heartbeat. The pulse velocity UDF allows for the simulation of the changing velocity of blood over time as it’s pumped by the heart, while the output pressure UDF modulates the pressure conditions to reflect systolic and diastolic phases at the outlet. These UDFs improve accuracy by introducing a timed component to the simulation, creating a more realistic model of blood flow, which significantly departs from a simplified constant flow simulation and influences stress and deformation results on vessel walls. By accounting for this dynamic behavior, engineers and scientists can better understand the impact on the blood vessel walls and predict the vessel’s biomechanical response.

    The simulation’s attention to blood as a non-Newtonian fluid seems imperative. How does this affect the analysis compared to assuming blood is a Newtonian fluid?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The choice to consider blood as a non-Newtonian fluid rather than a Newtonian one is crucial for accuracy in biological simulations. Non-Newtonian fluids, like blood, have a viscosity that changes under different flow conditions, which affects the flow profile, wall shear stress, and overall hemodynamics. Incorporating these characteristics lends a more realistic representation of how blood behaves under physiological conditions. This has implications on factors like predicting arterial wall stress or understanding the progression of vascular diseases.

    The course seems really detailed. I’m curious, does it also discuss how to implement custom UDF for simulations like blood flow where non-standard boundary conditions are present?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Yes, the course covers the application of User-Defined Functions (UDFs) to simulate non-standard boundary conditions such as pulsatile flow, which is especially relevant for replicating blood flow patterns in cardiovascular studies using Ansys Fluent.
