For reactors in critical situations, ’Loss of Coolant’ incidents require ensuring that the core and fuel rod claddings are properly cooled when water injection is triggered by safety monitoring systems. Cold water injections encounter vapour, leading to gas-liquid two-phase flows at high pressures and temperatures. Determining the two-phase flow regimes, existing in the zones of the vessel where cooling must be effective, is a key issue.
It is therefore crucial to predict the two-phase flow regimes as well as transitions between them such as from a ’separated’ to a ’dispersed’ regime where one phase is present as a set of individual elements such as bubbles or droplets.
The purpose of this PhD is to develop a fine-grained numerical model for gas-liquid two-phase flows, based on a fluid-mechanical to capture transitions between flow regimes and predict flow characteristics for given external conditions. The chosen numerical methods is the Smoothed Particle Hydrodynamics (SPH) method which uses a Lagrangian description of flow interactions between fluid particles within the domain.
In order to complete the research, candidates will ideally have or develop during PhD: Strong analytical skills; computation skills; programming; good level of UG maths for engineering; knowledge of Physics relevant to fluid mechanics and/or multi-phase flows.
