Drag coefficient calculations using the Cercignani–Lampis–Lord quasi-specular gas–surface interaction model have been used to derive modified closed-form solutions for several simple geometries. The key component of the modified closed-form solutions is a relation between the normal energy and normal...

cd = drag coefficient ρ = density of fluid (1.2 kg/m3 for air at NTP) v = flow velocity (m/s) A = characteristic frontal area of the body (m2) The drag coefficient is a function of several parameters like shape of the body, Reynolds Number for the flow, Froude number, Mach Numbe...
drag coefficient. The variability of the coefficients in the currently widely used drag form can be explained by the differences in wave steepness in the observations. A drag coefficient model with wind speed and wave steepness as parameters is proposed. An explanation for Kahma' s result that ...
separately.Based on the correlations of Stokes shape factor with particle sphericity in laminar and turbulent regimes,analytical equations for the terminal settling velocity and drag coefficient of non-spherical particles in transition regime have been obtained by using Ergun's theory for the resistance...
In addition, the model with the bulk drag coefficient gave much larger velocity values than measurements, but it could be improved by adding the bed friction effect and making choice of the depth-averaged velocity within the canopy layer. 展开 ...
A separate computation was done to estimate the area of the body, thus requiring a third coefficient (body area coefficient). Experimental data for t and s were collected for six athletes of the Italian National team in order to obtain the best-fit values for the unknown coefficients.RESULTS:...

In part 1 (Andreas and Claffey, this issue) we observed some characteristics of the neutral stability air-ice drag coefficient at a reference height of 10 m (CDN10) that had not been documented before. Our main conclusion was that wind-driven snow continually alters the sea ice surface; th...
