Destruction of Ukrainian dam threatens Zaporizhzhia
A Soviet-era dam downstream from the Zaporizhzhia nuclear power plant in southeastern Ukraine collapsed last evening, causing the water level of the Kakhovka Reservoir north of the dam to drop and raising new concerns over the already jeopardized safety of the Russian-occupied nuclear facility, Europe’s largest. The reservoir supplies water for, among other things, Zaporizhzhia’s cooling systems.

Rigorous and consistent formulations of basic equations of interfacial area transport were derived using correlation functions of the characteristic function of each phase and velocities of each phase. The turbulent transport term of interfacial area concentration was consistently derived and related to the difference between the interfacial velocity and the averaged velocity of each phase. Constitutive equations of turbulent transport terms of interfacial area concentration were proposed for bubbly flow. New transport model and constitutive equations were developed for churn flow. These models and constitutive equations are validated by experimental data of radial distributions of the interfacial area concentration in bubbly flow and churn flow.
