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.

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators
Advanced Robotics Research, EarlyView.We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.
