... on the simulations of three-dimensional CFD using three turbulence models, namely Realizable k-ε two-layer, Lag-EB k-ε and SST (Menter) k-ω. Spatial resolution limitations in the application simulation were identified via solution verification. The experimental data obtained from our experimental setup were used...

... the intentionally flooded reactor cavity and is in direct contact with the outer surface of the lower head. An experimental study along with a computational fluid dynamics (CFD) model are used in the present study to investigate the local convection heat transfer coefficient on curved heated upper walls during...

... and of the surrogate model predictions are analyzed. Conclusions are drawn which should better inform future uses of surrogate models in the context of their credibility.

..., and operate light water reactor nuclear power plants. Differences in form of the discretized equations and closure relationships used within the systems analysis codes versus those in higher-fidelity computational fluid dynamics (CFD) codes lead to correspondingly different techniques to verify and validate...

... computational and experimental analysis coupled with verification assessment is key to using these product structures in thermal hydraulics especially to address industrial requirements. Here the hydraulic properties are computed by performing three-dimensional CFD analyses using Star-CCM+. Gyroid TPMS...
