| dc.description.abstract | The quality of our indoor environment influences our mental and physical health. Fluid flow is a factor
that influences this, which can be analysed using computational fluid dynamics (CFD) software. In this
thesis the finite volume method (FVM) based software Star-CCM+ was used to model different type
of doors separating two zones, one containing a tracer gas mixture and the other containing air. The
Reynold-averaged Navier Stokes (RANS) equations were used with a k ����� turbulence model to solve for
3D compressible multi-component fluid flow, with an overset mesh being used for moving solids. For both
the verification model and the case model, a comparative analysis considering cumulative mass exchange
was performed. For the case model, thermal effects and human motion were also included. | en_US |
