Computer modelling of contaminants mobility in subsurface regions
thesis
posted on 2018-10-26, 10:39 authored by Diganta Bhusan DasOne of the keys to realistic mathematical modelling of any transport phenomenon is to
understand the fluid mechanics of the process correctly. However, this is a daunting task
for the subsurface flow systems: the geometry of the domain is irregular, the
physical/structural characteristics are not known with certainty and, to make the problem
further complicated, the processes often involve combined free and porous flow regions.
Modelling for combined free and porous flow under the ground is of significant practical
importance in many areas of water resources engineering. These include, for example,
water seepage and contaminant mobility through preferential flow channel boundaries,
groundwater rise and fall and flow circulation in the subsurface, permeable reactive
barrier technology and many other important transport processes. The presence of
impermeable or multiple number of permeable interfaces in the physical domains of the
combined free and porous flow sections and the aspect ratios between the sub-domains
may also significantly influence the fluid dynamics in such coupled systems. [Continues.]
