Soundiation-Acoustophoresis

Soundiation: a MATLAB GUI-based software used to predict the acoustic radiation force and torque, thereby the acoustophoresis of any axisymmetric particle under a plane wavefield or a user-customized transducer array.

Major features:

• The particle can be designed as arbitrarily axisymmetric geometry (by the mapping coefficients "c_n");
• The sound-hard (Neumann) and sound-soft (Dirichlet) boundary conditions are provided;
• The medium can be air or water;
• The arrangment of transducer array, as well as phase & amplitude transducer parameters support user-specified (optional).

Theoretical background:

• The partial wave expansion method [1];
• The translation addition theorem [2, 3];
• The conformal mapping technique [4, 5];

Initialization

The program support parallel computation (Refer to user manual in ./doc/user_manual for details).

The source codes are found in the ./src folder. To start the Soundiation GUI, add the folder path:

addpath('<folderpath>/Soundiation-Acoustophoresis-main/src');

Then, open the the Soundiation GUI by typing in Command Window (MATLAB):

main_interface;

Requirements

Soundiation has been tested with MATLAB2010a and above and should run on most personal laptops and desktop machines.

Documentation

• File arXiv_2202.04526 is a description preprint for the software.

• ./docs folder contains:

  • A numerical model (by COMSOL Multiphysics 5.5) to validate the calculation results, if needed;
  • A user manual.

• ./src folder contains:

  • All source codes (".m") and a GUI framework ("main_interface.fig") for the software.

• ./data file (example) folder contains:

  • An example of the user designed particle geometry ("particle_data.stl");
  • An example of the predicted dynamic data (namely "Myfilename.txt" by default).

  Note: By default, the above data files are automatically saved in the ./src folder.

Functionality

Major functionalities includes:

• Design a non-spherical particle and output a "particle_data.stl" file;
• Prediction of the acoustic radiation force and torque on non-spherical particles;
• Prediction of the dynamics (translational and rotational motions) of non-spherical particles above an user-specified transducer array (the dynamic data is saved in a "Myfilename.txt" by default).
