Thermochemical interaction of wood and polyethylene during co-oxidation in the conditions of thermogravimetric analysis

... in the conditions of thermogravimetric analysis // Reaction Kinetics, Mechanisms and Catalysis. 2020. DOI: 10.1007/s11144-020-01880-y In this work, using the methods of thermal analysis, we investigated the features of the oxidative decomposition of mixtures of polyethylene and sawdust (in different mass ratios). The results show that during the mixtures decomposition, the effects of interaction between wood and polyethylene are observed, which, apparently, are associated with the chain nature of ...

Hydraulic and gas-dynamic models of a steam-water mixture flow in a granular bed

Tairov E.A., Khan P.V. Hydraulic and gas-dynamic models of a steam-water mixture flow in a granular bed // Journal of Physics: Conference Series. Vol.1382. No.1. ID: 012101. 2019. DOI: 10.1088/1742-6596/1382/1/012101 The paper presents a comparative analysis of the hydraulic and gas-dynamic models of a steam-water mixture flow through a granular bed. The analysis is carried out using experimental data obtained at an inlet pressure of 0.6 - 15.5 MPa, flow quality of 0.002 - 0.3, and mass velocity...

Numerical study on the efficiency of biomass and municipal waste fixed-bed co-gasification

... composition, initial moisture of sewage sludge). Dependencies of gasification process characteristics are evaluated and compared with published experimental data. Fixed-bed downdraft process is investigated related to using of wood and sewage sludge mixtures. New results are obtained considering process efficiency dependence on input fuel composition, method is proposed to estimate acceptable fuel mixtures based on agglomeration and efficiency requirements. © The Authors, published by EDP Sciences....

A polytropic model of a critical two-phase flow in a bed of spherical particles

Tairov E., Khan P. A polytropic model of a critical two-phase flow in a bed of spherical particles // MATEC Web of Conferences. Vol.115. 2017. 4 p. DOI: 10.1051/matecconf/201711505007 https://www.matec-conferences.org/articles/matecconf/pdf/2017/29/matecconf_sts2017_05007.pdf The paper is concerned with a model of isenthalpic flow of vapor-water mixture in a fixed bed of solid particles. The mixture expansion process is considered to be polytropic. Similarly to the known problem of gas dynamics...
