The effect of drop evaporation on gas turbulence and heat transfer for two-phase flow behind sudden pipe expansion
Annotation
The effect of drop evaporation on turbulence and heat transfer in a two-phase separated axisymmetric flow was studied numerically. The comparison between the calculation data for evaporating and nonevaporating particles under otherwise identical conditions is given. In the zone adjacent to the wall, drop evaporation was shown to proceed most intensively and almost no suppression of turbulence was observed in this case. The turbulence level is close to that in a single-phase flow regime. In the flow core where virtually no evaporation occurs, there was a decrease in the gas turbulence level (down to $15\%$ compared to singlephase flow).
