“…Below are the results of mass and energy exchange by thermal decomposition of particles, that is, the evolution of volatile components. As stated above, the heat exchange between the particle and the gas causes the thermal decomposition of the particles according to the kinetic scheme (13), resulting in the evolution of volatile components. Figure 4 presents the evolution of the carbon monoxide volatile gas CO.…”

“…The research determines the temperature and pressure spectra of the flow in compressible turbulence. Friedlander et al 13 have used the FUN3D code to simulate a Reynolds‐averaged Navier–Stokes calculation of subsonic flow in an S ‐diffuser and transonic flow in a two‐dimensional (2D) diffuser using a Reynolds stress model. Reynolds simulations were demonstrated to give more accurate predictions of the diffusion flow fields compared to simulations using one‐ and two‐equation turbulence models.…”

The study of turbulent flow in mixtures consisting of gas and particulate matter is a current area of research among modern scientists. The main objective of this area is to prevent the reduction of burnout in flow‐through systems. Therefore, the purpose of this research is to develop a mathematical model of turbulent gas flow with solids to explore the structure of the combustion region in a channel with a partially open boundary to determine the interfacial interaction of the injection of a flat heterogeneous flow in a confined area and the influence of regime parameters on the ignition process. For this purpose, a modeling method was used, which involved using the fundamental laws of continuity of flow, conservation of energy, and the quantity of motion and matter, and an experiment was conducted to reconcile the proposed model with theoretical data. As a result of this work, a model based on the averaged Reynolds Navier–Stokes equations and an algorithm for solving a turbulent subsonic two‐dimensional flow in a heterogeneous medium based on an Euler–Lagrange representation have been developed. Thus, the effects of the parameters of entrainment, temperature, and component concentration on the combustion range and mixing intensity were determined. The proposed methodology can be applied to solve application problems of various kinds, for example, in the design of thermal power plants. The scope of the mathematical and numerical models developed is sufficiently broad that they are universal.
