Abstract
The numerical model for description of flow dynamics and heat transfer in an impinging axisymmetric gas-droplets jet is presented. The Eulerian model uses for computations of the impinging gas-droplets jet. In this paper the two-phase turbulent jet is numerically predicted by the set of axisymmetic Reynolds averaged Navier–Stokes equations. The flow structure and heat transfer in the gas-droplets impinging spray with low mass fraction of droplets (ML1≤1%) is studied numerically. Gas phase turbulence is modeled with the use of Reynolds stress transport model for two-phase flow. Droplets addition causes a significant increase in heat transfer intensity (almost twice) in comparison with a single-phase impinging air jet in the stagnation zone. In the region of wall jet the heat transfer intensity in the two-phase impinging jet decreases and approaches the value of a single-phase impinging jet.
