| 1 | CFD Study of Ejector Flow Behavior in a Blast Furnace Gas Galvanizing Plant显示文摘In recent years, there has been a growing interest toward Blast Furnace Gas(BFG) as a low-grade energy source for industrial furnaces. This paper considers the revamping of a galvanic plant furnace converted to BFG from natural gas. In the design of the new system, the ejector on the exhaust line is a critical component. This paper studies the flow behavior of the ejector using a Computational Fluid Dynamics(CFD) analysis. The CFD model is based on a 3D representation of the ejector, using air and exhaust gases as working fluids. This paper is divided in three parts. In the first part, the galvanic plant used as case study is presented and discussed, in the second part the CFD approach is outlined, and in the third part the CFD approach is validated using experimental data and the numerical results are presented and discussed. Different Reynolds-Averaged Navier–Stokes(RANS) turbulence models(k-ω SST and k-ε Realizable) are evaluated in terms of convergence capability and accuracy in predicting the pressure drop along the ejector. Suggestions for future optimization of the system are also provided. | Giorgio Besagni Riccardo Mereu Fabio Inzoli | 2015 | Journal of Thermal Science2015，24，1： | 4 |
| 2 | On the scale-up criteria for bubble columns显示文摘It is generally admitted that experimental data obtained in“laboratory-scale”bubble columns are representative of“industrial-scale”reactors if the well-known three“Wilkinson et al.scale-up criteria”are satisfied:(a)the diameter of the bubble column is larger than 0.15 m,(b)the sparger openings are larger than 1e2mm and(c)the aspect ratio is larger than 5.The aim of this communication is to contribute to the existing discussion.To this end,this communication collects relevant experimental investigation and include new experimental data:in particular,we have experimentally studied the combined effect of the aspect ratio(within the range of 1e15)and the sparger design(considering both“coarse”and“fine”spargers)on the gas holdup in a large-diameter and large-scale gas-liquid bubble column.The bubble column has been operated both in the batch mode and in the counter-current mode.Filtered air has been used as the gaseous phase in all the experiments,while the liquid phase has included deionized water and different aqueous solutions of organic(i.e.,ethanol)and inorganic(i.e.,sodium chloride,NaCl)active agents.It is found that the“Wilkinson et al.scale-up criteria”are valid for the air-water case in the batch mode for“very-coarse”spargers.Conversely,they are no more valid when considering different liquid velocity,and/or aqueous solutions of active agents,and other sparger openings. | Giorgio Besagni Lorenzo Gallazzini Fabio Inzoli | 2019 | Petroleum2019，5，2： | 2 |
