摘要

By analyzing the similarity between the viscosity-inertia compromise for single fluid turbu- lent pipe flow and the particle-fluid compromise in gas-solid fluidization, it is deduced that the variation- al criterion for dissipative structures dominated jointly by two sub-mechanisms(for instance, viscous ef- fect and inertial effect in turbulent flow; particle movement and fluid movement in fluidization)could be physically expressed as mutually constrained extremum between the individual extremum tendencies of the sub-mechanisms, and could thus be mathematically formulated as a two-objective optimization problem.
