Typical Model Studies

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

Summary

Fluid-structure interaction simulations accurately predict abdominal aortic aneurysm wall stress and wall shear stress. Solid stress simulations are adequate for maximum stress, but fluid-structure interaction is needed for precise wall shear stress analysis.

Area of Science:

  • Biomedical Engineering
  • Computational Fluid Dynamics
  • Medical Imaging

Background:

  • Abdominal aortic aneurysms (AAAs) pose significant health risks, necessitating accurate biomechanical modeling for diagnosis and treatment.
  • Patient-specific computational models are crucial for understanding AAA hemodynamics and mechanics.
  • OpenFOAM, a finite volume solver, is increasingly used for complex biomedical simulations.

Purpose of the Study:

  • To evaluate the accuracy of fluid-only, solid stress, and fluid-structure interaction (FSI) simulations in predicting biomechanical parameters in patient-specific AAA geometries.
  • To compare the results of different simulation approaches and determine their suitability for specific clinical applications.
  • To provide guidance on selecting appropriate simulation methods based on the desired outcome.

Main Methods:

  • Three patient-specific AAA geometries were used for simulations.
  • Fluid-only, solid stress, and FSI simulations were performed using OpenFOAM.
  • Fluid-only simulation results were validated against experimental data.
  • Comparison of stress and wall shear stress (WSS) between different simulation types.

Main Results:

  • OpenFOAM demonstrated good agreement with experimental data for unsteady flow in AAA.
  • Solid stress simulations underestimated maximum stress by up to 5.9% compared to FSI.
  • FSI simulations showed flow-induced pressure up to 4.8% higher than imposed systolic pressure in solid stress simulations.
  • WSS varied by up to 35% between fluid-only and FSI simulations.

Conclusions:

  • Solid stress simulations are sufficient for predicting maximum AAA wall stress.
  • FSI simulations are necessary for accurate prediction of AAA wall shear stress.
  • The choice between simulation methods should depend on the specific research question and parameters of interest.
