Abstract
At first the elongational stress is derived to be ρυ2, where ρ is the fluid density and υ is the local flow velocity. Then macromolecular chains elongated in the solution are assumed to be thin rods and to associate with each other due to mutual interactions, and Batchelor's theory of suspension of thin rods is utilized to obtain the elongational stress for dilute polymer solutions in the elongational flow. Finally, the velocity distribution along the flow direction is derived over the upstream region of converging flow. The results obtained are confirmed to agree with the experimental ones.
