| Abstract: | This article writes out optimizations target of dynaflow auto - cleaning helical twisted stripe's structure in horizontal refrigerating tube. The flowing fluid in the tube with spiral link is studied and theoretical calculation's expression of cleaning tonjue and drag coefficient and heat transfer Nusselt number of fluid body with link's structural parameter are established by means of theory associate with testing measure. The result of the dynaflow auto- cleaning helical twisted stripe's structure optimization's study in horizontal tube is talked. |
