a turbulent fluid is a complex nonlinear large system and it is impossible as well as unnecessary to make detailed study of the geometrical structure and dynamical behavior of its strange attractors.
with water as experimental fluid, the turbulent fluid resistance in the sk static mixer was measured and the experimental formula was regressed by this experiment.
以水为实验介质,对sk型静态混合器流体湍流阻力进行了实验测量,回归出实验公式。
calculated results show that the turbulent fluid flow intensively alters the shapes of temperature field and the solute distribution in thin slab.
