TWO KINDS OF LAMINAR FLOW IN POLYMER SOLUTIONS AND MECHANISM OF DRAG REDUCTION
-
Abstract: A brief review on the research work of drag reduction of dilutepolymer solutions is given in this paper. The new idea about polymer laminar flow and the mechanism of drag reduction based on the idea proposed by Harvard group are summarized systematically.
