“…Detailed phenomenon can be implemented in CFD models with which the scale-up calculation can be performed much easier and more effective in comparison with the traditional ways. [1,5] There are quite number of CFD-assisted scale-up studies in literatures for different processes such as fermentation, [6][7][8] coal combustion, gasification and burners, [9][10][11][12] bioreactors and bubble columns, [1,5,[13][14][15][16] gas cleaning and upgrading, [17,18] spouted and fluidized beds, [11,19,20] and crystallization reactors. [21] To mention few, Azuhata et al [9] have performed a CFD-based analysis of a coal burner to scale up from laboratory to pilot scale with 25 times higher coal feed rate.…”

For all industrial applications, predicting system characteristics and behavior plays a vital role before constructing costly and complex multi-physic systems. Correct and reliable predictions become even more important once the aim is to go from small- to large-scale processes to establish an industrial demonstrations. In this study, a CFD-based scale-up of HIsarna off-gas system based on the Eulerian–Lagrangian approach is investigated and detailed step in scale-up procedure is discussed. A three-dimensional CFD model is developed and validated based on the available pilot scale data and used to design and scale up the post-combustion chamber (also known as reflux chamber). Detailed kinetics for volumetric and gas–solid reactions are incorporated in validated CFD model with a special attention to the wall boundary condition and modeling. The effect of reflux chamber geometry, oxygen injection ports, oxygen injection flowrate, isolation wall thickness, and inlet flue gas composition on different system characteristics such as heat loss through the wall, CO–H2–carbon mixture conversion, flue gas, and wall temperature are investigated. The aim of the scaled up geometry, like pilot scale, is to achieve full combustion of unwanted species inside the reflux chamber to assure zero emissions from the off-gas system. Compared to the pilot scale, the scaled up reflux chamber is capable of handling and removing higher amount of unwanted species coming from the main reactor and therefore lower CO–H2 and carbon particle emissions, mainly due to a larger size which provides larger volume and residence time for volumetric and gas–solid reaction to proceed.

“…3.15 is intractable due to its high dimensionality. In our Lagrangian PDF code [ Raman et al ( , 2003[ Raman et al ( , 2004], Eq. 3.15 is expressed in terms of stochastic differential equations for so-called "notional"particles.…”

“…The procedure to calibrate the concentration measurements is described by [ Feng, H. et al (2005)]. in this study can be found elsewhere [ Liu, Y. et al (2004)]. The performance of this model is evaluated by comparing predicted single-point turbulence statistics with ensemble-averaged PIV data (which is equivalent to time-averaged data for this stationary flow).…”
