Abstract
Numerical solutions are obtained for transient response of water droplets to radiative heating. Results are presented for evaporation of polydispersed droplets in the solar radiation field. The evolution of the temperature and size of the droplet are determined. The results are discussed based on cloud droplet evaporation in the presence of absorbing inclusions.
Highlights
The interaction between radiation and water droplets results in the attenuation of radiative energy by scattering and absorption
Irradiation of polydispersed droplets by solar radiation is discussed
The time scales involved in the droplet evaporation under intense radiation is very small
Summary
The interaction between radiation and water droplets results in the attenuation of radiative energy by scattering and absorption. If the temperature increase is significant, the equilibrium of water vapor with a droplet will be perturbed and the droplet begins to vaporize. The change in the droplet size further alters the radiation transfer parameters. These processes are governed by the energy and vapor transport between droplets and the environment. This heating and subsequent evaporation of droplets in a radiation field are important in many areas, such as fog clearance and cloud processes (Ackerman et al, 2000; Koren et al, 2004). The effect of radiation absorption on the size distribution of polydispersed droplet is examined
