The flow in tight rod bundles is characterized by long-term, large-scale coherent patterns in
the stream-wise direction. In the present work, the issue of simulating these structures …

In this study, some well-known experimental studies related to forced, natural, and mixed
convections were used for validation of k-ε and k-ω turbulence models. For this purpose …

Turbulent mixing of hot and cold streams in T-junction geometries is a critical safety issue for
power plants, as temperature fluctuations have the potential to lead to high cycle thermal …

Computational fluid dynamics (CFD) is widely adopted to predict complex flows and to
inform the design of advanced engineering systems. In particular, the industry has seen a …

A STRUCTure-based (STRUCT) second generation (2G) URANS turbulence model is
presented in this paper and assessed on the simulation of unsteady turbulent flow, with …

An effective way to increase the volume of cargo transported by freight trains is to increase
their operational speed. The complex flow generated by trains moving through air has …

To address the issues of the existing hybrid models and to better address the industrial need
for a robust, grid consistent, and widely applicable hybrid model, an interesting new …

This work demonstrates a strategy for hybrid turbulence modeling that relies on parameters
identifying flow structures to regulate the model's level of scale resolution, independent of …

This paper details a CFD model of a 19-pin wire-wrapped sodium fuel assembly experiment
conducted at Oak Ridge National Laboratory in the 1970s. Model sensitivities were tested …

Growing interest in marine autonomous systems such as underwater gliders and
autonomous underwater vehicles (AUVs) has led to the increase of research on hydrofoil …
