Heat Conduction in PyroSim/FDS

May 10, 2017
FDS assumes one-dimensional heat conduction into the surfaces of solid obstructions. With proper modeling, you can couple the front and back face temperatures of an obstruction so that heat flows through the obstruction. This post demonstrates heat transfer through obstructions, including radiative and convective fluxes on the surface.  Read More...

Using PyroSim/FDS to Maximize Solar Panel Convective Cooling

April 18, 2017
Solar panels are most efficient if they operate at lower temperatures. We are installing solar panels on a workshop roof and the question arose, "What is the best solar panel spacing to maximize solar panel convective cooling?" This post uses PyroSim and FDS to evaluate some different solar panel mounting options to maximize solar panel convective cooling.  Read More...

Subway Station Passenger Movement using Pathfinder

March 27, 2017
This post demonstrates how to use Pathfinder to simulate movement in a subway station, with trains arriving and departing from the station. A growing list of features not specific to evacuation, such as occupant sources and assisted evacuation, make Pathfinder applicable to a much broader range of pedestrian movement problems. Read More...
