当空气中的固体或液体颗粒的分散体，如喷雾、烟或雾，受到辐射通量时，能量被颗粒吸收，颗粒的温度升高，能量从颗粒转移到空气中。如果颗粒具有可感知的蒸气压，则质量也被转移到气相。本文介绍了整个过程的理论研究结果。考虑仅限于球形颗粒和涡流转移可忽略不计的应用，即通常仅限于直径为100微米或更小的颗粒。
WHEN a dispersion of solid or liquid particles in air, such as a spray, smoke, or fog, is subjected to a radiant flux, energy is absorbed by the par-ticles, the temperature of the particles rises, and energy is transferred from the particles to the air. If the particles have an appreciable vapor pressure, mass is also transferred to the gas phase. This article presents the results of a theoreti-cal investigation of the over-all process. Consideration is limited to spherical particles and to applications in which eddy transfer is negligible—ie, gener-ally to particles of 100 microns or less in diameter.
