文摘

We investigate the drop size distribution in a local approach. This method allows estimation of droplet size with no constant fitting. Experiments show that the “typical value” for the TKE dissipation rate lies between the maximum and the mean value in the flow field. The “typical ε value” is discussed by physical arguments for the flow structure.
