A practical problem of pollutant migration has been studied for dierent concentration dierences and mass diusivities using the ยฎnite element method. The results indicate that the pollutant takes years to travel 10 m into the water-saturated soil when the mass diusivity and concentration dierences ar

Using Hermit basis functions with the finite element method offers a remarkably simple way to compute non-isothermal buoyancy-driven incompressible flow. The Hermite bases we use simplify the governing equation and strongly enforce the continuity equation. For this problem, we use a fourth-order C 1
Experiences relating to the application of finite element models for laterally averaged stratified flow are discussed and modifications to the basic approach are suggested that alleviate these difficulties. An example problem is used to demonstrate the revised model and to make a preliminary assessm
## Abstract In this paper, we propose a variational multiscale finiteโelement approximation for the incompressible NavierโStokes equations using the Boussinesq approximation to model thermal coupling. The main feature of the formulation in contrast to other stabilized methods is that we consider th
