The quantities related to the deposition reaction are highlighted in red. This FDS propane_flame_deposition.fds verification file is also listed below. Select the propane_flame_deposition.fds file, click Raw, and save the text file.Click the View on GitHub button at the top of the page, and search the repository for propane_flame_deposition.We will base our model on the propane flame deposition model that you can download from the FDS Validation and Verification page. In this post, we will replicate the deposition reaction given in Section 12.4. Then proceed to Section 12.4 and review the Special Topic: Aerosol Deposition. This post describes how to accomplish this using PyroSim.Īs background, review the introduction to Complex Stoichiometry in Section 12.2 of the FDS User Guide. Deposition cannot be defined using the Simple Chemistry model, instead, it requires the use of the Complex Stoichiometry framework. The post Complex Stoichiometry in PyroSim updates and replaces the contents of this post.įDS can model the deposition of smoke and aerosols onto solid surfaces. PyroSim 2018.2 now supports complex stoichiometry in the user interface.
