Discrete particle simulation of gas-solid flow in a blast furnace

Experimental observations revealed that the stagnant zone, which forms in the lower central part of a blast furnace, is an important feature of solid flow, and that it is affected strongly by gas flow. However, it is difficult to model this feature within the framework of continuum mechanics without empirical or arbitrary treatments. This paper reports the use of discrete particle simulation fo...

Heterogeneous Flow Structure in Gas-solid Risers: Continuous Modeling

Abstract Gas-solid riser flow exhibits strong heterogeneous structure in both axial direction and radial directions. Recent experimental studies reveal that the general radial solids concentration profiles present a double ring structure and the formation of a solid core region which have a relative higher concentration than the annulus region. This paper is focused on a comprehensive modeling ...

1 Detecting and Modeling Nonlinearity in the Gas Furnace Data

The Hinich (1982) bispectrum test for nonlinearity and Gaussianity indicates that the residuals of the Tiao-Box (1981) constrained and unconstrained VAR models for the gas furnace data reject the assumption of Gaussianity and linearity over a grid of bandwidths for estimating the bispectrum. These findings call into question the specification of the linear VAR and VARMA models assumed by Tiao-B...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
