Aerodynamic Phenomena of Controlling Passive Flow of a Time‐Independent Ground Vehicle Under the Scope of Optimally Slanted Rear Wing‐Spoiler Combination

Engineering Reports
Notwithstanding the abundance of different expository efforts by the engineers and scientists of the aerodynamic—transonic domain for the ever‐beseeched question of whether a supercar needs a rear spoiler or a rear wing, the query requires further ...

DDES-Informed Development of a Helicity-Based Turbulence Model: Validation on Corner Separation and Aeronautical Flows

Aerospace
Accurate prediction of separated flows remains a critical challenge for Reynolds-Averaged Navier–Stokes (RANS) simulations, primarily due to the tendency of standard turbulence models to overpredict separation.

Comparison of Propeller and Self-Propulsion Performance of a Submarine Using RANS and LES Turbulence Models

한국해양공학회지
Underwater radiated noise (URN) from submarine propulsors requires reliable flow prediction as a prerequisite for cavitation and acoustic analyses. This study validates a computational fluid dynamics (CFD) workflow to predict the propeller open-water ...

Mixing Time Prediction in a Ladle Furnace

Metals
This paper presents a study on the effectiveness of two turbulence models, the large eddy simulation (LES) model and the k-ε turbulence model, in predicting mixing time within a ladle furnace using the computational fluid dynamics (CFD) technique.

Renormalization Group Approach as a Symmetry Transformation for an Analysis of Non-Newtonian Elastic Turbulence

Fluids
Symmetry transformation methods are widely used in fluid flow problems. One such method is renormalization group analysis. Renormalization group methods are used to develop a macroscopic turbulence model for non-Newtonian fluids (Oldroyd-B type).

Numerical Simulation of Foulings on the Marine Vessels Body and Application of Newly Recommended Techniques to Reduce the Resulting Drag Force

نشریه مهندسی دریا, 2016
In this research, the effects of foulings on the outer surface of a marine vessel have been studied using the Computational Fluid Dynamics (CFD) methods. To this end, a proper turbulence model was considered and validated for the simulations.
