Modeling fuel flowing into a drain
« on: July 01, 2020, 10:54:21 am »

I'm trying to model a fuel fire on a sloped surface. (fuel spill on a bridge) The flow will lead to a drain.  Is there anyway to model the burning fuel flowing into a drain in PyroSim?

At first glance, there are a couple of problems. A sloped surface can't be modelled. (It would look sloped in PyroSim, but would be stair-stepped in FDS. It's not possible to have anything move in FDS. You could create a series of burner vents to progressively appear on the descending steps to simulate the fuel flow, but you would be prescribing the events, FDS would not be modelling them.
