| 英文摘要 | The simulation of internal-loop airlift reactors is challenging because complex meso-scale structures exist in different sections of the reactor, separated by the draft tube. This paper reports on the computational fluid dynamics (CFD) simulation of internal-loop airlift reactors using a new drag model derived from the dual-bubble-size COBS) model, an extended energy-minimization multi-scale (EMMS) approach for gas-liquid flows. Compared with the traditional Schiller-Naumann (S-N) correlation, the new model improves the simulation of gas holdup in the riser and downcomer significantly. In particular, gas holdup and circulation of two-phase flow can be modeled successfully using the new model, whereas traditional drag models such as the S-N correlation show an absence of gas in the downcomer. The simulation demonstrates the advantage and potential of this new model for internal-loop airlift reactors.
