Actuator line URANS-to-LES comparison of single and tandem floating offshore wind turbines [PDF]
Wind Energy ScienceThe motion of floating offshore wind turbine platforms strongly affects wake development, influencing energy production, farm layout, and turbine loads. Unlike fixed-bottom turbines, floating turbine wake interactions are less understood and require high-

An URANS Simulation of the Kelvin-Helmholtz Aerodynamic Effect over the Ahmed Body
International Journal of Automotive Science and Technology, 2021 The reduction of energy consumption of cars is always a significant issue in automotive design. Turbulent flow around a car body is very difficult to simulate accurately due to the complexity of the flow conditions around the body, such as complex flow ...

A numerical study of unsteady cavitation on a hydrofoil by les and URANS method
, 2015 In this paper, the unsteady cavitation phenomena on a NACA0015 hydrofoil is numerically simulated by unsteady Reynolds-Averaged Navier-Stokes (URANS) method and Large Eddy Simulation (LES) in single-fluid approaches to multiphase modelling, respectively.

Energy Science &Engineering, EarlyView.Turbulence intensity from 1% to 25% was parametrically tested on a three‐bladed H‐type Darrieus rotor across five tip speed ratios (TSRs) using two‐dimensional URANS. The optimal TSR proved the most efficient and most robust operating point simultaneously, with Cp losses capped at 5.8% even at TI = 25%. ABSTRACT The effect of inlet turbulence intensity

Energy Science &Engineering, EarlyView.Three‐turbine guided Savonius arrays installed along highway corridors extract up to 697 J under multi‐vehicle wake conditions when spaced 12 rotor diameters apart—68% more than compact arrangements. Guide vanes boost output by 80–120%, and interior turbines respond most strongly to spacing, governing overall array performance. ABSTRACT Highway‐induced

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Plants harbor complex microbial communities that are fundamental to their health and productivity. Among them, endophytic fungi such as Purpureocillium lilacinum establish mutualistic associations, offering dual benefits as plant growth promoters and biocontrol agents.
