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

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

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

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

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

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

During the hot extrusion process, a cylindrical pre-heated billet is inserted into a container and is forced by a hydraulic press to flow through a shaped die in order to obtain, as final product, a profile with a constant cross-section (Fig.1). Aluminum extrudates have become prominent ... En savoir plus

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

This study investigates the shock boundary layer interaction occurring at the base of a double sharp fin. The base geometry is of particular interest, with comparisons made between flat and semi-cylindrical bases. The flow field is characterized via numerical simulations and ... En savoir plus
