Summary
Synthetic vocal fold models show flow-induced vibration coupled with upstream tubes. A slightly compressible model accurately simulated this acoustic coupling, unlike incompressible models.
Area of Science:
- Acoustics
- Fluid Dynamics
- Biomechanics
Background:
- Flow-induced vibration in synthetic vocal fold models is known to acoustically couple with upstream flow supply tubes.
- Understanding this coupling is crucial for accurate voice production modeling.
Purpose of the Study:
- To investigate the acoustic coupling between synthetic vocal fold model vibration and upstream flow supply tubes.
- To evaluate the suitability of different flow models for simulating this phenomenon.
Main Methods:
- Utilized a finite element model incorporating flow-structure-acoustic interactions.
- Varied the length of the upstream duct to analyze coupling effects.
- Compared incompressible and slightly compressible flow models.
Main Results:
- The slightly compressible flow model demonstrated acoustic coupling between fluid and solid domains, aligning with experimental findings.
- The incompressible flow model did not exhibit this acoustic coupling.
- The length of the upstream duct influenced the observed coupling.
Conclusions:
- A slightly compressible flow model is appropriate for simulating acoustically-coupled flow-induced vibration in synthetic vocal fold models.
- Accurate simulation of vocal fold dynamics requires considering fluid compressibility effects.

01:28Standing Waves in a Cavity
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:
01:22Couette Flow
Couette flow represents the flow of fluid between two parallel plates, with one plate fixed and the other moving with a constant velocity. This configuration allows for a simplified analysis using the Navier-Stokes equations, which govern fluid motion under conditions of viscosity and incompressibility. For Couette flow, the assumptions include a steady, laminar, incompressible flow with a zero-pressure gradient in the flow direction. This flow type is beneficial for understanding shear-driven...
01:24Turbulent Flow
Turbulent flow is characterized by unpredictable fluctuations in velocity and pressure, which result in a chaotic fluid movement distinct from the orderly patterns of laminar flow. While laminar flow is governed by smooth, parallel layers with minimal mixing, turbulent flow exhibits highly irregular, three-dimensional patterns. This behavior arises due to instabilities in the fluid's velocity profile, and amplifies as the flow velocity increases. Minor disturbances, known as turbulent spots,...
01:06Forced Oscillations
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.
01:17Sound as Pressure Waves
Sound waves, which are longitudinal waves, can be modeled as the displacement amplitude varying as a function of the spatial and temporal coordinates. As a column of the medium is displaced, its successive columns are also displaced. As the successive displacements differ relatively, a pressure difference with the surrounding pressure is created. The gauge pressure varies across the medium.
The pressure fluctuation depends on the difference in displacements between the successive points in the...

01:30Application of Integration: Problem Solving
The process of breathing involves the periodic intake and expulsion of air, known as the respiratory cycle, which typically lasts about five seconds. Modeling the volume of air inhaled into the lungs as a function of time provides insight into both the dynamics and efficiency of pulmonary ventilation. This volume is determined by integrating the airflow rate over time, which captures the cumulative effect of air entering the lungs.Sinusoidal Model of AirflowAirflow during respiration is not...
