ODT

This code implements the One-Dimensional Turbulence (ODT) model for turbulent reacting or nonreacting flows.

Documentation

Detailed documentation is available here. More information on the theory and application of ODT is available here.

A short video overview summarizing downloading, building, running, and processing the code is shown here.

Dependencies

ODT Code

• Cantera: open-source suite of tools for problems involving chemical kinetics, thermodynamics, and transport.
• Yaml: input file format. This installation is conveniently built into the ODT build process.
• Cmake 3.12 or higher
• (OPTIONAL) Doxygen: builds documentation.

Post-processing

Post-processing data produced by ODT and ODT is processed via Python 3 scripts. We recommend Python 3.2 or higher. Scripts may not function properly using Python 2.x. The following packages are required and can be installed via pip3:

• numpy
• scipy
• matplotlib
• glob
• yaml
• sys
• os

Directory structure

• build: build the code
• data: contains all data files output during a simulation
  • The code will generate a subfolder with a name corresponding to case name specified in the run script in the run folder.
    • This case subfolder will contain subfolders input, runtime, data, and post, which contain the input data files, runtime output, simulation data files, and post-processed data, respectively.
• doc: contains documentation files
• input: contains case input files
  • Other input files include a Cantera mechanism file in the user_gas_mechanisms folder and an optional restart.yaml file.
• post: contains post-processing scripts and files for given case types
  • Output is placed in data/caseName/post. These are mostly Python files. Some cases also include experimental data files for comparison and plotting.
• run: contains the code executable odt.x and several run scripts
  • The user specifies inputDir as the path to the input file containing the case to run and specifies a case name for variable caseName. Files are created and copied into data/caseName, as noted above.
• source: contains source code (including header files) and CMakeLists.txt files
