This implies that the frictionvelocity and roughness length are both enhanced significantly for the breaking waves when compared with the incipient breaking cases.
However, results obtained in this study show a clear decrease of with frictionvelocity.
The wind frictionvelocity u* has been used extensively as a key parameter in quantifying wind-wave interaction processes.
In particular, inner-layer scaling, based on the frictionvelocity a t the trailing edge of the aerofoil, should be applicable to the inner wake.
The approach that was found to be most convenient for obtaining an estimate of the frictionvelocity made use of the measured mean ice thickness.
Here u* is the wind frictionvelocity and c is the phase speed of the wave components.
The model is assumed to include, as a specific case, zero frictionvelocity when instability of the sublayer is of pure free-convection nature.
In the first case, as the frictionvelocity increases, a threshold is reached above which grains begin to roll and hop over the surface.
Similarly, the influence of a small change in the frictionvelocity, u*, was investigated.
The fluctuating part is formed by a product of the frictionvelocity and a signal which is assumed to be periodic along the streamwise direction.
Simulations in figure 9(c) show how the parameter for the flux decay with height varies with frictionvelocity u and particle size.
The effects of particle density on the saltation trajectory could not be studied here independently of the more significant effects of frictionvelocity and particle size.
Hence, the present results are also scaled with the inner variables (frictionvelocity and kinematic viscosity), and are shown in figure 10.
Quantitatively, the frictionvelocity changed from about 0.37 m/s for the latter to about 0.51 m/s for the breaking waves, for each of the wavelengths investigated.
This occurred not because the wavelength for a given now condition was significantly different, but rather because the frictionvelocity was larger over the rough surface created by the wave.
It states that the mass transport of sand is proportional to the third power of the frictionvelocity.
