Abstract
Researchers have investigated the interaction of fluids on porous media however
those studies have largely been an investigation of significantly greater quantities
of fluid or large scale fluid interactions with porous media. There has been little
research done that probes the behavior of droplets on porous media at a micro -
scale level. The purpose of this study was to examine the behavior of sessile
micro - drops on porous media to be specifically applied to chemical warfare
scenarios.
The results from large scale fluid interaction studies cannot be applied to micro -
scale scenarios. Micro - droplets of chemical agent simulates and porous media
of varying relative porosities were used to directly observe relations or used to
find properties necessary for furthering the Agent Fate Project.
The relative porosities of silica gel, glazed tile, glass beads as well as gradients
of sand, concrete and asphalt were found initially. Porosity was a factor in nearly
all of the properties and observations. Chemical simulates including; ethylene
glycol, methyl salicylate, diethyl malonate, and others were delivered to the
porous media. Quantitative experiments using the simulates and porous media
were used to determine properties such as; phase (relative) permeability, vapor
diffusivity, reaction rate, and evaporation (mass loss).
