The heat released as a fire burns is distributed to the environment primarily through convection and radiation. In a simulation, you specify the fraction of the fire total heat release rate that should be assigned to radiation. But, when you check the FDS output files you may see a different fractional amount of radiation in the Q_RADI column of data. This post will explain why these values are different, and what you should expect the Q_RADI data to represent. Read More »
This release of PetraSim improves support for Petrel geometry, HydrateResSim, and import of vertical internal boundaries.
This version of PetraSim uses version 1.8.0_05 of the JavaVM.

This post discusses using PyroSim/FDS to model jet fans, with the eventual goal of modeling parking garages. It starts with some background information that was useful to me in helping me understand the problem. In preparation for a parking garage simulation, we first focus on a free jet, comparing the results of a mesh convergence study with the experimentally derived correlations for centerline velocity decay. This and the future garage simulation should help you decide whether PyroSim is applicable to your jet fan application.
