A numerical model for predicting free round gas-droplet polydispersed jet using Euler approach is presented. The numerical study of the effect of droplet size and its mass fraction on the flow structure, heat transfer and turbulence of the gas phase is carried out. The Reynolds stress model is used for predicting of the turbulence of the gas phase. The polydispersity of the dispersed phase has the little effect on the flow structure and heat transfer in jet in this range of initial parameters. Gas-droplet round jet becomes more narrow and long-range compared to the singlephase one. The addition of evaporating droplets leads to the suppression of turbulence of the gas phase. The maximal suppression is shown in the initial zone of the jet, where the mass fraction of dispersed phase is the biggest and droplet size decreases slightly due to evaporation.
Keywords: free round gas-droplet jet, polydispersity, droplet evaporation, flow structure.
