N/A Characteristics of droplet vaporization at high ambient pressures and temperatures which are supercritical conditions is studied numerically by formulating one dimensional vaporization model in liquid dodecane and air. Modified Soave-Redlich-Kwong state equation is used to condider real gas effect. Non-ideal behavior of properties at near critical and supercritical conditions is considered in the high pressure condition. Characteristic spatial distribution of properties with various conditions of pressure and temperature is evaluated in order to understand vaporizing evolution.

There are many methods to move or reduce the static electricity which often causes disasters in industry, etc. The methods may include grounding of a potentially-charged body, use of antistatic materials, humidification of an atmosphere, use of static electricity eliminators. Among those methods, the one utilizing antistatic materials is widely used in the industrial fields due to its effectiveness and inexpectiveness. In Korea, safety regulations and technical standards are not sufficient for applying to industrial fields as electrostatic disaster prevention measures due to the shortage of practically verified and reliable data. The propose of this paper is to examine the electrostatic characteristics of the antistatic materials and non-antistatic ordinary materials under the various conditions of different temperature and humidity.
