摘要

Polymer induced turbulent drag reduction achieved by adding minute amounts of high molecular weight DNAs (λ- and calf-thymus DNAs: CT-DNA has a molecular size of about 75.7 kbp with polydispersity while the monodisperse λ-DNA possesses 48.5 kbp) was investigated using a rotating disk apparatus (RDA). By putting emphasis on effect of CT-DNA concentration, its DR characteristics were compared with that of λ-DNA possessing monodisperse molecular weight characteristics based on both DR efficiency and a mechanical degradation under turbulence. The DNA chains having much higher molecular size than that of λ-DNA are observed to be more susceptible to mechanical degradation in a turbulent flow. This result was verified via electrophoresis.
