Can poroelasticity predict the response of fluid-impregnated foams to axial compression ?

A. Beaudoin¹, D. Sanchez¹, A.E. Ennazii¹
¹Institute P', University of Poitiers, Poitiers, France

Started in March 2020, the SOFITT project (Saturated Open-Cell Foams for Innovative Tribology in Turbomachinery), funded by the ANR (French National Research Agency), aims to develop reliable, high-performance, and environmentally friendly solutions for the guidance and support systems ...

Evaluating Changes in Pulmonary Blood Vessel Shear Stress and Pressure Post-Pneumonectomy

Mia Long¹, Aaron B. Waxman², Farbod N. Rahaghi², Songbai Ji¹, Solomon A. Mensah¹
¹Worcester Polytechnic Institute, Worcester, MA, USA
²Brigham and Women’s Hospital, Boston, MA, USA

A pneumonectomy is an invasive, high-risk surgical procedure performed to remove the right or left lung. Although this may be a life saving procedure for some patients, it has high morbidity rates and many complications post-pneumonectomy. Pneumonectomies result in the heart’s entire ... En savoir plus

Developing a Growth Prediction Model of Abdominal Aortic Aneurysms via Computational Fluid Dynamics

George N. Pittas¹, Wei Yin¹
¹Stony Brook University, Stony Brook, NY, United States

Abdominal Aortic Aneurysms (AAAs) are balloonings of the descending aorta. Surgical intervention only occurs when the aneurysm growth exceeds a certain threshold, which is slightly different between men and women. Early-stage patients are often asymptomatic, and there is no prediction ... En savoir plus

A Multifaceted Model Exploring the Role of Mucus and Shear Stress in Intestine

Ibrahim Erbay¹, Yury Rochev¹
¹CÚRAM, SFI Research Centre for Medical Devices, University of Galway, Galway, Ireland

The intestine, a muscular, tubular organ within the digestive system is responsible for the final stages of food processing. The cyclic material transport generates a shear stress on the intestinal lining known as epithelium. Recently, the application of shear stress on epithelial cells ... En savoir plus

Drag Reduction and Vortex-Induced Vibration Mitigation Via Optimizing Aerodynamic Characteristics

Raed Bourisli¹, Adel Alshayji¹
¹Kuwait University

This study focuses on optimizing the lengths of various structural components around a cylinder to minimize drag. Using COMSOL Multiphysics, numerical simulations involving Laminar Flow were performed. Key components optimized include an arrowhead positioned upstream and two flaps ... En savoir plus

Efficiency and Stability Trade-offs in FSI Simulations of Coronary Artery Blood Flow

E. Guleryuz[1], A. Taha[1], S. Koric[1], Q. Lu[1], M. Vellakal[1]
[1]National Center for Supercomputing Applications (NCSA), University of IL at Urbana-Champaign., USA

Some of the most common fluid-structure interaction (FSI) applications in biomedical research include blood flow in the veins and arteries. COMSOL Multiphysics® simulation software offers two main multiphysics schemes for FSI problems: partitioned (segregated) and monolithic (fully ... En savoir plus

Study of Compliance Mismatch within a Stented Artery

G. Coppola, and K. Liu
Lakehead University, Department of Mechanical Engineering, Richmond, Hill, Ontario, Canada

The objective of this paper is to study the effects of compliance mismatch in a stented artery. COMSOL Multiphysics is used to tackle this challenging problem involving fluid-structure interaction. The particular effects studied in this paper are the radial displacement of the artery ... En savoir plus

PCCP Profiling and Tube Wave Analysis of WRE Signal

N. Chowdhury[1], Z. Liao[2], and L. Zhao[1]
[1]Department of Electrical & Computer Engineering, Ryerson University, Toronto, ON, Canada
[2]Department of Architectural Science, Ryerson University, Toronto, ON, Canada

Acoustic wave propagation due to the breakage or slippage of reinforced wire in water-filled prestressed concrete cylinder pipe (PCCP) attracts interest in non-destructive pipe testing. Current practice of acoustic emission (AE) detection and wire-break related events (WRE) recognition ... En savoir plus

Coupled Fluid-Structural Analysis of Heart Mitral Valve

A. Avanzini, and G. Donzella
Department of Mechanical and Industrial Engineering, University of Brescia, Brescia, Italy

The mitral valve apparatus is a complex and refined mechanism located between the left atrium and the left ventricle of the heart which can manifest various kinds of pathologies. In order to support identification of potentially critical conditions resulting from some typical ... En savoir plus

Modeling and Simulation of Control Valves via COMSOL Multiphysics®

S. Zhuang [1],
[1] CAEaid, Inc., Austin, TX, USA

Valves are widely used to control fluid flow in various engineering applications. It’s crucial to study the flow characteristics inside the valve and the fluid-structure interaction between the fluid and valve’s sleeve for design, optimization and improvement of valves. However, because ... En savoir plus
