Computational Analysis of Inspiratory and Expiratory Flow in the Lung Airway
Peshala P. T Gamage, Fardin Khalili, Azad Md. K +1
Inspiratory and expiratory flow in a multi-generation pig lung airway was numerically studied at a peak tracheal flow rate corresponding to a Reynolds number of 1150. The model was…
A coupled CFD-FEA study of the sound generated in a stenosed artery and transmitted through tissue layers
Fardin Khalili, Peshala P T Gamage, Ibrahim A Meguid +1
A new computational approach for simulating the blood flow induced sound generation and propagation in a stenosed artery with one-sided constriction was investigated. This computat…
Verification of Turbulence Models for Flow in a Constricted Pipe at Low Reynolds Number
Fardin Khalili, Peshala P. T. Gamage, Hansen A. Mansy
Computational fluid dynamics (CFD) is a useful tool for prediction of turbulence in aerodynamic and biomedical applications. The choice of appropriate turbulence models is key to r…
Numerical Modeling of Pulse Wave Propagation in a Stenosed Artery using Two-Way Coupled Fluid Structure Interaction (FSI)
Peshala P. T Gamage, Fardin Khalili, Hansen A Mansy
As the heart beats, it creates fluctuation in blood pressure leading to a pulse wave that propagates by displacing the arterial wall. These waves travel through the arterial tree a…
The Influence of the Aortic Root Geometry on Flow Characteristics of a Bileaflet Mechanical Heart Valve
Fardin Khalili, Peshala P. T. Gamage, Hansen A. Mansy
Bileaflet mechanical heart valves have one of the most successful valve designs for more than 30 years. These valves are often used for aortic valve replacement, where the geometry…
Prediction of Turbulent Shear Stresses through Dysfunctional Bileaflet Mechanical Heart Valves using Computational Fluid Dynamics
Fardin Khalili, Peshala T. Gamage, Hansen Mansy
There are more than 300,000 heart valves implanted annually worldwide with about 50% of them being mechanical valves. The heart valve replacement is often a common treatment for se…
Seismocardiographic Signal Timing with Myocardial Strain
Amirtaha Taebi, Richard H. Sandler, Bahram Kakavand +1
Speckle Tracking Echocardiography (STE) is a relatively new method for cardiac function evaluation. In the current study, STE was used to investigate the timing of heart-induced mo…
Heart Rate Monitoring During Different Lung Volume Phases Using Seismocardiography
Amirtaha Taebi, Andrew J Bomar, Richard H Sandler +1
Seismocardiography (SCG) is a non-invasive method that can be used for cardiac activity monitoring. This paper presents a new electrocardiogram (ECG) independent approach for estim…
An Adaptive Feature Extraction Algorithm for Classification of Seismocardiographic Signals
Amirtaha Taebi, Brian E Solar, Hansen A Mansy
This paper proposes a novel adaptive feature extraction algorithm for seismocardiographic (SCG) signals. The proposed algorithm divides the SCG signal into a number of bins, where…
Hemodynamics of a Bileaflet Mechanical Heart Valve with Different Levels of Dysfunction
Fardin Khalili, Peshala P. T. Gamage, Hansen A. Mansy
Heart disease is one of leading causes of mortality worldwide. Healthy heart valves are key for proper heart function. When these valves dysfunction, a replacement is often necessa…
Grouping Similar Seismocardiographic Signals Using Respiratory Information
Amirtaha Taebi, Hansen A Mansy
Seismocardiography (SCG) offers a potential non-invasive method for cardiac monitoring. Quantification of the effects of different physiological conditions on SCG can lead to enhan…
Analysis of Seismocardiographic Signals Using Polynomial Chirplet Transform and Smoothed Pseudo Wigner-Ville Distribution
Amirtaha Taebi, Hansen A Mansy
Seismocardiographic (SCG) signals are chest surface vibrations induced by cardiac activity. These signals may offer a method for diagnosing and monitoring heart function. Successfu…
Pressure Loss and Sound Generated In a Miniature Pig Airway Tree Model
Md Khurshidul Azad, Amirtaha Taebi, Joseph H Mansy +1
Background: Pulmonary auscultation is a common tool for diagnosing various respiratory diseases. Previous studies have documented many details of pulmonary sounds in humans. Howeve…
