Description

technical field [0001] The invention relates to a particle fluid two-phase flow system, in particular to a method for measuring the non-uniform structural parameter distribution of the particle fluid two-phase flow system. Background technique [0002] Particulate fluid systems are widely used in process industries such as petroleum catalytic cracking and coal combustion. In a two-phase flow reactor, the particle fluid presents a complex non-uniform flow structure, which is the key to the study of the flow, mass transfer and heat transfer process in the reactor. The distribution and evolution of heterogeneous structural parameters in the reactor are the core concerns of reactor design, operation, control and scale-up. [0003] At present, the description of the flow parameters in the reactor is usually the engineering experience correlation method or the computational fluid dynamics (CFD) method. Empirical correlation methods are mainly based on the analysis of limited exp...
