Wind speed dynamical model in a wind farm [PDF]

IEEE ICCA 2010, 2010
This paper presents a model for wind speed in a wind farm. The basic purpose of the paper is to calculate approximately the wind speed in the vicinity of each wind turbine in a farm. In this regard the governing equations of flow will be solved for the whole wind farm. In ideal circumstances, the dynamic model for wind flow will be established.

A measurement of the wind speed on a brown dwarf [PDF]

Science, 2020
High winds in an extrasolar atmosphere Brown dwarfs are objects intermediate in mass between large planets and small stars, and their atmospheres share many characteristics with gas giant planets. Wind speeds in Solar System gas giant atmospheres can be derived by comparing the planet's rotational periods in the ...
