โฆ Synopsis
A new model based on Levich's three-zone model is developed to discuss the turbulent hear and mass transfer in drag-reducing solutions. The proposed model, which has no adjustable parameters and is represented in an explicir form, provides satisfactory predictions of the maximum heat and mass transfer reduction in smooth and rough pipes. The mass transfer to a disk rotating in drag-reducing solutions is also discussed using the proposed model.

Addition of polymer molecules to solvents influences the turbulence characteristics and in turn it influences the macromixing and micromixing behaviour in such flows in a profound way. The mixing lengths in pipe flows of dilute polymer solutions are known to be several times larger than those for Ne
