Description
When a hazardous substance is diffused, it is necessary to identify pollutant source and respond immediately; for example by cleaning up and/or evacuation. Reverse simulation, which is the solution of the transport equation in negative time, is a method for identifying pollutant source with CFD. Then the negative diffusion amplifies numerical errors and reverse simulation cannot be carried out. We introduced a method, which is to apply a low-pass filter operation to concentration flux in RANS analysis, to improve numerical stability. In this paper, we introduce reverse simulation result in cavity flow and survey the dependence of reverse simulation accuracy.
