Scientific scale-up of gas liquid stirred reactors is one of the key problems needed to be solved promptly in the further development of petrochemical industries. Fluid flow, mixing, transfer and reaction processes in gas liquid stirred reactors are to be investigated by using experiment, theoretical analysis and numerical simulation approaches. The key problems for scientific scale-up of gas liquid stirred reactors, mechanism and model of gas liquid micromixng and interaction, the relations between flow structure and function of gas liquid system, coupling calculation approach of fluid flow, transfer and reaction processes, are expected to be broken through. The physical and mathematical models and related numerical approaches with high efficiency of fluid flow, mixing, transfer and reaction processes of gas liquid reactor will be established. The fluid flow, mixing, transfer and reaction processes in gas liquid reactors will be coupling simulated numerically. The principle and rules of gas liquid stirred reactor optimum regulation will be clarified. The theory and approach of scientific scale-up of gas liquid stirred reactors will be constructed. The results will promote the development of large scale high efficiency gas liuqid stirred reactors, upgrade the petrochemical industries technology, and put forward to the quantization of chemical engineering.
