CFD simulation of influence of configuration on the performance an external reactor

In this research, the simulation of two phase bubbly flow in an external airlift reactor using computational fluid dynamics (CFD) was carried out. The CFD simulation covered a variety ofdesign parameters including the length of connection tubes ( c L ), height of riser and downcomer ( h L ). Three different c L and h L were used to determine the effects of them on hydrodynamic of an external reactor. The results demonstrated increasing c L and h L seemed to increase liquidvelocity and decrease the overall gas holdup. The simulation results were compared with the experimental results and were found good agreement
