Gas-inducing reactor is a sort of gas-liquid reactor operated easily and has been widely applied in many chemical industries, environmental engineering and biotechnological engineering for its predominant mass transfer performance and the low power consumption and cost due to the absent of external compressor. In the gas-inducing reactor involving gas-liquid two-phase flow system, the mixing, mass transfer and heat transfer processes are very complicated. Many problems need to be solved in theory. The critical impeller speed for the onset of gas induction,rate of gas induction,power consumption,gas holdup and mass-transfer coefficient of the self-inducing reactor are discussed, and research process on the CFD simulation of self-inducing reactor is also discussed, these are useful for the scale-up of self-inducing reactor.
