| 中文摘要 | It has been widely recognized that input parameters affected the results of Eulerian simulation of gas-solid flow. In this study, a comparative study was performed to study the effect of input parameters on the hydrodynamics of gas-solid flow in a countercurrent downer reactor. It was concluded that the input parameters of the Eulerian model, including restitution coefficients, specularity coefficient, and drag correlation, have a major effect on the bed hydrodynamics, in accordance with previous studies on other types of gas-fluidized beds. More importantly, we show that it is possible to match the experimental data either by changing the wall boundary conditions or by correcting the interphase drag force. Therefore, there is no unique way to tune the input parameters to fit the experimental data. This study indicated that researchers have to pay great caution when selecting input parameters and highlighted the requirement of stringent experimental tests of the state-of-the-art Eulerian models. |
