摘要: Abstract Studies have been made of the motion dye streamers on surface a sphere in close packed cubic array spheres. At Reynolds number 82 completely steady flow is observed with nine distinct regions reverse flow. The same type pattern also 200 where unsteady. patterns are described by identifying singular points limiting streamlines. Contact were to be saddle these
