Abstract

Abstract: The spectral method, ie. Galerkin method and the pseudo-spectral method wereused to solve the diffusion equation of the distribution function in configurational space for amultibead-rod model and N-S equation respectively. The properties of the coherent structure ina plane mixing layer with rigid-rodlike polymer additives and the most probable orientations ofthe multibead rods were obtained simultaneously. The results indicate that adding polymer tothe Newtonian fluid will make flows have stronger vorticity...

Key words: multibead-rod molecular model, mixing layer, coherent structure, spectral method
