Numerical simulation of subcooled flow boiling and application to the EAST plasma facing components

The paper describes numerical simulation approaches to subcooled boiling and investigates their application to EAST plasma facing components(PFC). A two-fluid model implemented with a wall boiling model based on a wall heat flux partition algorithm was used to solve control equations for mass, momentum and energy, which coupled with additional closure relations describing the exchange of two phases at the interface. A user-defined function(UDF) was written to define the source terms of phase exchange and specify the customized parameters of the multiphase. And the proposed two-fluid model was verified by experimental data of Lee et al. Also the simulation of the EAST plasma facing components was done with subcooled flow boiling method. (author)
