A MODIFIED FINITE ELEMENT METHOD FOR SOLVING THE TIME-DEPENDENT, INCOMPRESSIBLE NAVIER-STOKES EQUATIONS. PART 1: THEORY*
Three examples will be presented to demonstrate the performance of the scheme described in Part 1 of this paper.1 Two are isothermal (T = 0) and two-dimensional, and one of these is steady and theExpand

Solving the incompressible Navier--Stokes equations using consistent mass and a pressure Poisson equation
We derive and demonstrate a new technique for solving the time- dependent incompressible Navier--Stokes equations using low-order (bilinear) finite elements. The scheme is based on using theExpand

A review of recent field tests and mathematical modelling of atmospheric dispersion of large spills of Denser-than-air gases
Large-scale spills of hazardous materials often produce gas clouds which are denser than air. The dominant physical processes which occur during dense-gas dispersion are very different from thoseExpand
