NUMERICAL MODEL OF WIND-INDUCED ENTRAINMENT IN A DOUBLE-DIFFUSIVE THERMOHALINE SYSTEM

A low Reynolds number k-e model has been used to predict the wind-induced entrainment in a double-diffusive system. The calculated results are compared with experimental results from wind-induced entrainment in a finite length tank and with shear-induced entrainment in an annular tank. Overall agree...

Zusammenfassung:A low Reynolds number k-e model has been used to predict the wind-induced entrainment in a double-diffusive system. The calculated results are compared with experimental results from wind-induced entrainment in a finite length tank and with shear-induced entrainment in an annular tank. Overall agreement is good for wind speeds less than 10 m / s. Above this value, multidimensional effects tend to dominate. The scale of the turbulence at the surface is found to significantly affect the entrainment rate. This indicates that the suppression of waves on the surface can significantly reduce the rate of entrainment.
