Mathematical modeling of the process of making fireproof protective coverings by two-phase jets

Reporter: Milosevic H.

     The mathematical modeling of the process of making fireproof protective coatings reduces to the consideration of a problem of the interaction of a two-phase turbulent jet with a plane wall. The second phase represents a fine-fraction mixture of the coke and magnesite particles, and when impinging on the wall they can both stick to it and reflect from it. The reflected particles near the wall interact with the carrier gas and with the impinging particles thus forming a narrow layer of particles with the increased particles concentration, which is usually called as a screening layer.
      The computation of such a flow in a jet was performed within the framework of a continual model. For the description of gas flow the averaged Navier-Stokes equation system and model of turbulence have been used.
