论文摘要
弹性惯性湍流方案中Fene-P流体的二维通道流量模拟揭示了从混乱到稳定的行驶波的不同机制,该机制采用了箭头结构的形式。这种连贯的结构在驱动EIT的聚合物/流相互作用中提供了新的见解,在一组受控的数值实验中观察到了这些见解,并研究了弹性和湍流动能之间的转移。
Two dimensional channel flow simulations of FENE-P fluid in the elasto-inertial turbulence regime reveal distinct regimes ranging from chaos to a steady travelling wave which takes the form of an arrowhead structure. This coherent structure provides new insights in the polymer/flow interactions driving EIT, which are observed in a set of controlled numerical experiments and the study of transfer between elastic and turbulent kinetic energy.
