The thermal hydraulics part (steady VOL. 46, NO. 6, JUNE 2009 574 state and transient) is restricted to HTRs and to two spatial dimensions. The code can simulate the reactor operation from the initial core towards the equilibrium core. In Turkey, the temperature and the flow distributions ...
The discretized pressure–velocity coupling equation is solved via the SIMPLEC method; the nodal Green-Gauss method processes the gradient term; the central difference method and second-order upwind scheme discretize the diffusion and convection terms; and the discrete continuous equilibrium method in the...
The numerical algorithm has been implemented in an advanced, general-purpose CFD code, FLUENT, and validations have been carried out for a range of steady-state and unsteady flows, including a 2D axisymmetric orifice, a 3D fuel injector, a radial liquid pump, and a vane pump. The results ...
