Abstract
The CFD investigations of distribution of emissions usually lack the validation aspect. This paper presents a benchmark test model which could be used as an effective and adequate validation tool for the CFD studies involving the different investigations of distribution of emissions in the indoor environment. The experiments were conducted using the full scale experimental test room. The time-dependent concentrations of propane and carbon dioxide at different locations inside the room were measured by flame ionization detectors and infrared photometers respectively. The Reynolds Averaged Navier Stokes equations of continuity, momentum, turbulence model (k-epsilon) and concentration were solved using ANSYS CFX 15.0. The simulation results and the experimental results were found to be in good agreement.
