Case study of wave dependent drag coefficient in the Baltic Sea
Meteorologische Zeitschrift, 2000 Proper estimation of air flow over sea waves plays a key role in wave, storm surge, wind field prediction. Most hydrological models assume the drag coefficient Cd to be dependent only on the local wind speed. However this is a simplification.

The drag coefficient of cylindrical spacecraft in orbit at altitudes greater than 150 km [PDF]
The spacecraft of the Geopotential Research Mission (GRM) are cylindrical in form and designed to fly with their longitudinal axes parallel to their direction of flight. The ratio of length to diameter of these spacecraft is roughly equal to 5.0.

Superfluid drag of two-species Bose-Einstein condensates in optical lattices
, 2012 We study two-species Bose-Einstein condensates in quasi two-dimensional optical lattices of varying geometry and potential depth. Based on the numerically exact Bloch and Wannier functions obtained using the plane-wave expansion method, we quantify the ...

Drag Force on Submerged Flexible Vegetation in an Open‐Channel Flow
Water Resources ResearchThe movement of submerged flexible vegetation leads to an increase in resistance to the stream flow. In this study, a formula that can directly calculate the drag force on a highly flexible submerged vegetation, called Ceratophyllum, by using the ...
