[en] A component-scale thermal-hydraulics analysis module, CUPID has been being developed for a transient three-dimensional two-phase flow analysis of nuclear reactor components. CUPID is based on a two-fluid, three-field model, which is solved by using an unstructured finite volume method. The three fields in the CUPID code represent a continuous liquid, an entrained liquid, and a vapor field. At present the two liquid fields in the CUPID code are assumed to be in a thermally equilibrium state. In this paper, non-equilibrium energy equations for droplets and continuous liquid fields were implemented and assessed. In addition, the shared memory parallelism for the CUPID code was tested using a quad-core CPU personal computer
