Evaporation of HD Droplets From Nonporous, Inert Surfaces in TGA Microbalance Wind Tunnels

Abstract

The environmental fate of chemical warfare agents (CWAs) is important because the contact or vapor hazard is critical input for models used to support decisions on the level of individual protection at fixed sites. Two different microbalances, configured in a wind-tunnel geometry, were used to measure the evaporation and desorption rates from surfaces. The overall experimental design covers several neat and thickened agents and several material surfaces. The initial elements of the experimental design reported here include chemical warfare agent HD on inert, nonporous surfaces, [i.e., glass and aluminum, and on an inert, porous surface (i.e., standardized aggregate from concrete and asphalt pavements)]. Two or three environmental temperatures, wind speeds, and relative humidity values were studied.
