خلاصه مقاله:
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
