RADIATIVE EFFECTS IN A SEMI-TRANSPARENT LIQUID CONTAINING GAS BUBBLES
Following from: Radiative transfer problems in nature and engineering
The problem treated in this section arises in the case of water cooling of very hot surfaces. A practical example is provided by the delivery of water to the surface of the corium pool in the case of a nuclear reactor severe accident as reported by Bechta et al. (2000). Because of high temperature (2000-3000 K), the main part of the thermal radiation of the pool surface is in the near infrared, where water is semi-transparent. As a result, a considerable part of the radiation is absorbed not in the thin surface layer of water but in the volume far enough from the interface (Dombrovsky, 2003, 2004). The volume heat source can lead to generation of vapor bubbles, which affect the radiation transfer. In the complete physical problem statement, one should take into ...
