Abstract:
A numerical analysis of the flow structure and thermal efficiency of a gas-droplet jet injected through a radial annular slot into a transverse single-phase air flow is performed. The calculations are performed using the axisymmetric RANS approach in the following range of variation of the main parameters of the two-phase flow. Gas turbulence is described using the Reynolds stress component transfer model recorded taking into account the two-phase flow. An increase in the blowing ratio in the range of $m$ = 0.5–4 causes a significant increase in the separation region length by almost 3 times. An increase in the blowing ratio leads to an increase in the friction coefficient.
