Study of mass transfer characteristics of an experimental cutting zone cooling device
Incoming article date: 24.11.2021A computer mathematical model was developed to predict the course of working processes in the device. To estimate the reliability of the obtained model, the study of mass-exchange characteristics of the experimental cooling device was carried out. Analyzing the graphs of mass-exchange characteristics of the model and the experimental cooling device it is possible to conclude about their correspondence. The conducted tests allowed to reveal three characteristic zones of distribution of two-phase gas-liquid flows arising in the working zone of the atomizer at the atomizer's output in the steady-state operation mode. It is proved that the optimum air pressure at the inlet of the vortex chamber can be considered as 0.10...0.15 MPa.
