One of the most excellent tools to predict sound or noise propagation is considered to be CFD. ANSYS Fluent is a powerful tool that can come to help. The implemented models in this software can predict even the smallest-frequency noises to the highest-frequency sound waves, which may be beyond human hearing but still damage the surrounding environment. After passing this Acoustic Model Training Course, you are ready to claim yourself as an Acoustic CFD Simulation expert.
What do you learn in this Acoustic Model Training Course?
In this course, you will thoroughly learn how to simulate acoustics around any structure and investigate the sound wave propagation within any domain. Different acoustic simulation models, including FW-H, Wave Equation, and Broad Band Noise, are explained in detail, along with step-by-step instructions on performing simulations in Fluent. You will first learn about each model’s basics and then learn tricks and tips on performing the exact and accurate acoustic simulation.
This training course is presented so that it is as practical as possible so that the graduates can work well with this software to generate high-fidelity acoustic simulations after the end of the course.
This course contains 5 video lessons and a final project as an exam to get the Acoustic Certification.
This course is divided into five main lessons and some sub-lessons. You strongly recommend that you do not skip any of the sections even if you feel you know the content.
In this lesson, you will first see a general introduction to acoustics and an overview of available acoustic simulation models in ANSYS Fluent. This section contains the following subsections:
- Overview of acoustics and aero-acoustics
- Introduction to acoustic simulation models
- Introduction to Direct acoustic simulation method
- Introduction to Hybrid acoustic simulation methods
- Ffowcs Williams and Hawkings (FW-H)
- Wave equation
- Introduction to Broad Band Noise acoustic simulation method
- Overview of significant sound wave quantities
In this lesson, you will learn about the FW-H acoustic model by performing a simple project by investigating the sound waves around a 2D cylinder. This section contains the following subsections:
- Overview of the FW-H model and its applications and limitations
- Acoustic waves export options
- Defining the sources and receivers of sound waves
- Acoustic model parameters
- Defining the correct time step size based on CFL and Frequency values
- Extracting FFT plots
In this lesson, you will learn about the Wave Equation acoustic model by performing a simple project investigating the sound waves around a 2D cylinder. This section contains the following subsections:
- Overview of Wave Equation model and its applications and limitations
- Acoustic waves export options
- Wave Equation options
- Sponge regions and basic shapes
- Extracting graphical data and FFT plots
In this lesson, you will learn about the Broad Band Noise acoustic model by performing a simple project investigating the sound waves around a 2D cylinder. This section contains the following subsections:
- Overview of Broad Band Noise model and its applications and limitations
- Overview of Linearized Euler Equations (LEE)
- Extracting graphical data
This is the last session, and in this lesson, you will learn how to simulate practical and real problems using FW-H and Broad Band Noise models. In this session, you will learn to simulate sound propagation due to the rotating motion of a horizontal wind axis turbine (HAWT). Next, we will compare lesson 5 and lesson 6 with each other so that you would obtain an in-depth understanding of acoustic simulations using ANSYS Fluent.
