Interaction of a turbulent two-phase jet with a plane wall. (English) Zbl 0929.76056

Summary: We consider the problem of the impingement on axisymmetric sub- and supersonic turbulent two-phase jets of a perfect gas escaping from a Laval nozzle onto a plane wall. The flow in such jets is governed by the averaged Navier-Stokes equations and the \(k\)-\(\varepsilon\) model of turbulence, which takes into account the force and heat interaction between the gas and particles. The reflection of the impinging particles from the wall is allowed, which leads to the formation of a screening layer of particles, reducing the intensity of their sedimentation on the wall. For the computation of the particles’ motion we use two approaches – the continual approach, and the Lagrangian-Eulerian approach.
