Modeling Outdoor Air Pollution and the Urban Form
… thesis develops a solver for aerial pollutant transport by adding a passive-scalar transport equation to buoyantBoussinesqPimpleFoam, the OpenFOAM transient solver for buoyant, turbulent flow of incompressible fluids, with Reynolds Averaged Navier-Stokes (RANS) turbulence modeling. It then …

Quantification of Mixing in Microchannels
… the degree of mixing: (a) via calculation of a passive scalar transport equation, (b) by following fluid particle trajectories and calculating the statistics. The first approach suffers from presence of numerical diffusion. The second approach is usually used to only obtain qualitative …

Theoretical and numerical aspects of advection-pressure splitting for 1D blood flow models
… system of one-dimensional (1D) blood flow equations with a passive scalar transport equation. Our analysis involves a two-step framework that includes splitting at the level of partial differential equations (PDEs) and numerical methods for discretizing the ensuing problems. This study is …

Passive Scalar Transport by Non-Smooth Incompressible Fluids: Mixing and Vanishing Viscosity
… through rigorous mathematical analysis of the passive scalar transport model. Our investigation centers on the behaviour of fluid flows characterised by vector fields of lower regularity—a crucial feature in understanding turbulent dynamics. Through careful examination of these flows in various …
