Jason E. Floyd


This report summarizes FDS development and support activities performed during the three year grant period of 70NANB8H8161. A brief overview of the major and minor accomplishments are provided below. More detailed discussions follow in the remainder of this report. Major accomplishments during the grant include: Implementing a new scheme for tracking species; Implementing a new framework for combustion modeling; Adding an HVAC network model; Adding soot deposition capabilities and Release of 3 minor and 12 maintenance versions of FDS (a summary is Appendix A). Minor Accomplishments Some of the notable minor accomplishments include Improvements to droplet evaporation; Improvements to the computation of thermal physical properties; Extended database of gaseous and liquid properties; Readability improvements to the input file and Reorganization of inputs. The appendices to this report contain a summary of FDS releases (Appendix A), a summary of all commits to the FDS repository (Appendix B), a summary of all Issue Tracker issues responded to by the author (Appendix C), and a summary of all research publications produced by the author.
