Etymology
From iso- + Ancient Greek δύναμις (dúnamis, “power”). Coined by Jack W. Reed in 1975.[1]
Noun
isodyn (plural isodyns)
- An isoline connecting places at which an equal amount of wind power is available near ground level on average.
1979, “Synthesis of National Wind Energy Assessments”, in Dorothy J. De Renzo, editor, Wind Power: Recent Developments, page 59:Lockheed purposely avoided isodyns and chose to construct maps showing the estimated values of wind power for each station.
1989, J.O. Bockris, B. Dandapani, J.C. Wass, “A Solar Hydrogen Energy System”, in Advances in Solar Energy, page 218:Values of wind power are given in units of watts per square meter (of rotor swept area), along isodyns, or curves of constant power. These maps indicate only the total wind power available in the wind; the actual wind power extracted by a particular machine will be some fraction […]
Usage notes
Available wind power is proportional to the cube of wind speed, meaning that an isodyn map will differ from an isotach map.
