Some Observations on the Flow Characteristics of Certain Dilute Macromolecular Solutionsged jets, flow around spheres, and wall-attachment experiments..The primary effect of the additives in turbulent boundary layer flow is to cause a thickening of the viscous sublayer adjacent to a wall, the structure of the remaining portion of the boundary layer being little changed.

Drag Reduction in External Flows of Additive Solutionsstudies concerning diffusion and entrainment of jets with additive solutions flowing into a turbulent stream of pure Water have been conducted. The experiments include tests with additive solutions of various concentrations and different channel velocities. The drag reduction obtained in these exper紧张过度 发表于 2025-3-31 23:46:51
