Mathematical Model of Nonisothermal Turbulent Flow of Gas Suspension in a Pipe on the Basis of the Mixed Eulerian–Lagrangian Representation
Annotation
A mathematical model of nonisothermal turbulent flow of a gas suspension in a pipe is formulated on the basis of the mixed Euler–Lagrange representation. The testing of the model revealed good agreement of the calculation results with experimental data and with the data obtained using the continuum model developed by us previously. The use of two essentially different (continuum and mixed) approaches to the simulation of dusty flows leads to nearly identical results for the fields of averaged velocities and temperatures and for characteristics such as the coefficient of accommodation of the tangential component of the velocity and the intensity of the particle collisions with the wall surface.
