To eliminate the tiny ice crystals in the dynamic supercooled water ice-making systems, developing a model, analyses the melting process of the tiny ice crystals in turbulent water, presents a method calculating the melting time and analyses the relation between the melting time and minimum eddy scale and water temperature.

Total pressure pulsation intensity and eddy scale,which are the primary parameters used for describing the pulsation intensity and the size of the distorted flow field,affect the stall margin of engine greatly.

Eddy scales were calculated upon those flow data that were obtained through the total pressure distortion tests, and characteristics of the eddy scales were presented in order to improve the distortion test and investigate the effect of eddy scale to engine stability.

By performing eight experiments with a high resolution barotropic model,which is integrated for 36 hours,the interaction between a mesoscale vortex and a typhoon vortex is investigated with its effect on the variation of typhoon intensity.

ased on observational data and a mesoscale numerical model (MM4), the numeric simulational results of a deep mesoscale vortex at high level which related to a heavy rain event are presented.

The rising branch of the Jet secondary circulation resulted in a surface mesoscale vortex.
