The existing difference in the models used to describe the burning rate of solid fuel particles, and, accordingly, the difference in the constants appearing in them, determines the relevance of the formulation of the relation between the constants known from the literature and the parameters that must be set in programs for CFD modeling of heat and power processes. This, in particular, relates to modeling the combustion of solid fuels in the well-known program ANSYS FLUENT. The paper outlines a possible approach to solving this problem. Bibl. 5, Fig. 3.

In this paper, we use the research methods of sintering cup.On the basis of the determination of solid fuel particle size composition and the distribution in the mixture. During the sintering process, respectively, 5min, 10min, 15min, 20min interrupt the test, by dectecting the distribution of solid fuel in the mixture to study the migration phenomenon of solid fuel during the sintering process. The results showed that: during the sintering process, the main migration of the fuel is the migration of fine particles, including the fuel migration of 0.25-0.5mm grain size, part of the 0.5-1mm grain size and a small amount of-0.25mm grain size,but most of the fuel migrated will be re-adsorbed, about 0.11% of the fuel with the air flow through the material layer, the migration of fuel to ease the state of segregation in the vertical direction along the material layer, so that cause actual participation in the combustion of the fuel content in line along the height direction of the material layer.

Abstract A simple model of behaviour of a single particle on the bulging membrane was presented. As a result of numerical solution of a motion equation the influence of the amplitude and frequency of bulging as well as the particle size on particle behaviour, especially its downstream velocity was investigated. It was found that the bulging of a membrane may increase the mean velocity of a particle or reinforce its diffusive behaviour, dependeing on the permeation velocity. The obtained results may help to design new production methods of highly fouling-resistant membranes.
