Abstract
application/pdf
The gas-liquid mixing in the vicinity of the nozzle submerged in liquid to inject gases is an important process with respect to the commencement of chemical reactions and heat transfer in jets. The characteristics of the flow and the mixing were investigated concerning the super sonic jets of nitrogen injected into water through an orifice-type nozzle. The static and the total pressures, and the static and the stagnation temperatures in the jets were observed in the vicinity of the nozzle exit. In the case of the under-expansion discharge, the total pressure had an axisymmetric circular peak, similar to the radial profiles of those in the nitrogen-air super sonic jets. On the basis of the homogeneous two-phase flow model, some kinetic quantities were calculated using the pressures and the temperatures observed. The mass flux of water was evaluated to be highest in the peak region of the total pressure. It is probable that the gas-liquid mixing is most active in that region.
