A collaborative research project established between the University of Tennessee (UT) computational fluid dynamics (CFD) lab and the Federal Aviation Administration (FAA) Civil Aerospace Medical Institute (CAMI) sought to validate CFD prediction of the environmental control system (ECS)-generated ventilation velocity vector field with induced mass transport. The results of the velocity field validation exercise were published previously. An FAA Cooperative Research and Development Agreement (CRADA) project generated an experimental database of time-dependent inserted mass distributions in the CAMI Aircraft Environmental Research Facility (AERF). The companion CFD mass transport simulations were conducted at the UT CFD Lab using both commercial and proprietary computer codes. This paper reports the qualified results of the mass transport validation exercise.
