添加剂分子结构对减阻性能的影响及减阻效果的试验结果

本文首先分析了高分子结构对减阻性能的影响,然后通过试验研究找到了一种可供食用的新型湍流减阻添加剂(代号为PSA)。它易溶于水,在通常流动雷诺数下具有15%左右的减阻效果,为在食用系统和生物医学等某些特定领域中应用添加剂减阻技术开辟了新的前景。

THE INFLUENCES OF MOLECULAR STRUCTURE OF ADDITIVE ON PROPERTIES OF DRAG REDUCTION AND EXPERIMENTAL RESULTS

In this paper, the influences of polymer structure on friction reduction effect are analysed. And then, a new kind of drag reducing additive (PSA), which nonpoisonous and eatable, is obtained by experiments and researches. The PSA additive is soluble readily in water and has good effect on drag reduction. No doubt, the PSA can be employed to reduce the frictional drag in turbulent flow systems of food-stuff liquids. And it is possible to exploit the potentiality of biomedical applications of the drag reducing agent (PSA) in future. We are convinced that PSA will make an immeasurable contribution to the fields of food-stuff and biomedicine.
