Embodiment 1
[0096] This embodiment provides a method for measuring flow parameter distribution in a particle fluid two-phase flow reactor, the method comprising the following steps:
[0097] (1) According to the physical parameters and operating conditions of the fluid, initialize the flow field and boundary conditions; the initial flow field and boundary conditions are to specify the structural size, Particle size, particle density, fluid density, fluid viscosity, superficial fluid velocity, and particle flow flux;
[0098] (2) Calculate the mass conservation equation and the momentum conservation equation in each space micro-element, read the velocity distribution and concentration distribution in the space micro-element, and use the parameter u for the velocity distribution and concentration distribution in the space micro-element g , u p and ε g means, among them, u g Indicates the real velocity of the fluid in the space element, u p Indicates the real velocity of the solid in the...
