Assessment of a hybrid finite element and finite volume code for turbulent incompressible flows
HydraTH is a hybrid finiteelement/finitevolume incompressible/lowMach flow simulation code based on the Hydra multiphysics toolkit being developed and used for thermalhydraulics applications. In the present work, a suite of verification and validation (V&V) test problems for HydraTH was defined to meet the design requirements of the Consortium for Advanced Simulation of Light Water Reactors (CASL). The intent for this test problem suite is to provide baseline comparison data that demonstrates the performance of the HydraTH solution methods. The simulation problems vary in complexity from laminar to turbulent flows. A set of RANS and LES turbulence models were used in the simulation of four classical test problems. Numerical results obtained by HydraTH agreed well with either the available analytical solution or experimental data, indicating the verified and validated implementation of these turbulence models in HydraTH. Where possible, we have attempted some form of solution verification to identify sensitivities in the solution methods, and to suggest best practices when using the HydraTH code.
