Insights into electron wind force by a helical dislocation reconfiguration [PDF]

open access: yesiScience, 2023
Summary: Many efforts for decades have been made to explore electron wind force, produced by electric current itself under electropulsing treatment. However, the clear evidence of this force is hard to separate from Joule heating. Here we study a helical

Wind Influence on Ship Manoeuvrability – a Turning Circle Analysis [PDF]

open access: yesTransNav, 2021
Ship manoeuvrability is a wide term which consist of number of various parameters. Knowing the influence of these parameters on ship manoeuvrability is a first condition to ensure and maintain safe navigation.

Experimental Study on Wind Loading Characteristics of Trains under Stationary Tornado-like Vortices

open access: yesBuildings, 2022
The risk of trains being hit by tornadoes in China continues to increase due to the increasing density of railway lines and the shortening of the train departure intervals and the increasing probability of extreme weather phenomena caused by global ...

Wind Affecting Berthing Operations [PDF]

open access: yesTransNav, 2020
Almost every voyage culminates in a manoeuvre to berth the ship safely along a quay or wharf. During this phase a ship is affected by a number of factors, one of them being wind.

Discussion of Design Wind Loads on a Vaulted Free Roof

open access: yesWind, 2022
This paper discusses the wind loads for designing vaulted free roofs based on a wind tunnel experiment, in which the wind force coefficients for the main wind force resisting system and the peak wind force coefficients for cladding are considered.

Analysis and Evaluation of Manoeuvrability Characteristics of Polish Ferries m/f "Polonia" and m/f "Gryf" [PDF]

open access: yesTransNav, 2013
The paper describes some specific manner of M/F "Polonia" manoeuvring at the Ystad harbour where she is regarded to be "over maximal ship" and also M/F "Gryf" manoeuvring at Trelleborg, taking part into consideration the effect of wind pressure into the ...

Vibration Reduction Strategy for Offshore Wind Turbines

open access: yesApplied Sciences, 2020
The operational environment of offshore wind turbines is much more complex than that of onshore wind turbines. Facing the persistent wind and wave forces, offshore wind turbines are prone to vibration problems, which are not conducive to their long-term ...

Hydrodynamics and sediment transport in Poyang Lake under the effects of wind and backflow

open access: yesHydrology Research, 2023
The ecology of the aquatic environment in Poyang Lake, the largest fresh lake in China, is notably impacted by the backflow from the Yangtze River, which conveys a high flux of sediments.

Why the Coriolis force turns a wind farm wake clockwise in the Northern Hemisphere [PDF]

open access: yesWind Energy Science, 2017
The interaction between the Coriolis force and a wind farm wake is investigated by Reynolds-averaged Navier–Stokes simulations, using two different wind farm representations: a high roughness and 5 × 5 actuator disks.
