Abstract
The problem of removal of high heat flux in unsaturated packed beds due to supplying water is of concern in variety of engineering applications such as fire fighting problem and post-accident boiling of fluids within nuclear reactor debris. In this paper, the characteristic of heat transport in unsaturated packed beds including vaporization of supplying water has been investigated experimentally. It was found that the cooling process of packed bed due to supplying water droplet strongly depend on the mass flux and temperature of supplying water droplets, and, pressure of vapor phase in packed bed.
