Abstract
The purpose of the research project is to investigate two-phase flows that could appear during accidents in the process and energy systems. Investigations will be focused on the following topics:
- Analyses of the results of the tests performed on BETHSY integral experimental facility. These tests represent a diminished coolability of exothermal system due to loss of coolant and ensure the cooling with two-phase natural circulation. With improvement of the two-fluid flow models and methods for the two-phase flow modeling a good agreement of our calculations with experimental data is expected;
- Improvements of the existing one-dimensional two-fluid models of two-phase flow in the region of fast transients where the characteristic time scale is determined by the sonic velocity. The use of a more accurate numerical scheme will enable more detailed analysis of the correlations that are crucial for fast transients.
