Abstract

The frame is the leaks in secondary/tertiary heat exchangers. Nowadays with CANOP code it is possible to know state variables of fluids and the void fraction of their mixing. The interfaces are too numerous to be followed individually. The diffuse interfaces method does not allow to access to the interfaces total area. Its influence on heat and on momentum transfers between the phases added to pressure effects are of the
The tracking of disperse phase estimation will allow to access to :
- an accurate interfacial area by the knowledge of the evolution of the disperse phase population and its localization inside of the flow,
- bubble population generated,
- droplet population generated.

The proposed work consists in the development of a mesh level model for disperse phases tracking and its implementation within CANOP code in order to have a better estimation of the exchanges between the phases.
