In this post we replicate examples from the FDS User Guide, the FDS Verification Guide, and the FDS Validation Guide. The FDS User’s Guide, Section 13.2.2 “Complex Stoichiometry”, provides several examples of complex stoichiometry. To use multiple-fuel reactions (or other complex reactions) in an FDS simulation, it is necessary to specify the gas species and stoichiometry of the reactions. This post demonstrates how the new user interface capability can be used to represent multiple fuels and other complex reactions. Previously, PyroSim supported the FDS single-fuel, “simple chemistry” combustion model but complex stoichiometry required some manual input by the user. PyroSim version 2018.2 will support complex stoichiometry in the user interface. To follow along with this tutorial, download the relevant files here.
