Kinetic theory of drag on objects in nearly free molecular flow

Sengers, J.V.; Lin Wang, Y.-Y.; Kamgar-Parsi, B.; … - In: Physica A: Statistical Mechanics and its Applications 413 (2014) C, pp. 409-425

Using an analogy between the density expansion of the transport coefficients of moderately dense gases and the inverse-Knudsen-number expansion of the drag on objects in nearly free molecular flows, we formulate the collision integrals that determine the first correction term to the...

On the influence of changes in the drag relation on surface wind speeds and storm surge forecasts

Zweers, N.; Makin, V.; Vries, J.; Burgers, G. - In: Natural Hazards 62 (2012) 2, pp. 207-219

In this study it is investigated how uncertainties in the magnitude of the drag coefficient translate into … stress is linear in the drag coefficient. However, in the NWP model the wind speed is not fixed and increasing the drag in … in the wind stress and relative changes in the drag coefficient depends on the wind speed. For 10-m wind speeds larger …
