Simulation of Flow Structure by Velocity Profile

It is proposed to determine the main parameters of the structure of flows in objects by velocity profile without taking response curves using the indicator method in heat and mass transfer apparatuses and reactors. A formula is derived for calculating the variance (central moment of the second order) and the flow structure function for a half-open vessel. An algorithm is also proposed for calculating the average residence time, the Peclet number of longitudinal diffusion for a one-parameter diffusion model, the number of cells and the differential response function of a combined model with a sequential connection of ideal displacement and mixing zones for a cell model. Moreover, calculation of the distribution density of the differential and integral response curves corresponding to a given velocity profile is provided.
