Productivity Increase

The growing demand for water-soluble polymers of the acrylic series causes the researchers' interest in the synthesis of these compounds, which ultimately allows solving the tasks of the productivity increase, finding ways to improve the quality of final products, developing new highly efficient technological processes for the synthesis of these substances and their application as soft medicinal forms.

Dilute Polymer Solutions

Experiments are described in which the velocity profiles of axisymmetric jets are measured in water and in dilute solutions of water-soluble polymers. The ambient fluid and that entering through the nozzle were homogeneous. The similarity characteristics of velocity profiles including a linear variation of centre-line velocity with the inverse of the distance from the nozzle were unaltered by these substances. On adding large polyethylene oxide molecules to the system the jet spread at an increased angle, possibly due to the entrainment rate being enhanced by an increase in turbulent elasticity for polyethylene oxide solutions. It is also postulated that additives which had no effect on the velocity were not large enough to influence the small microscale eddies in which the energy to activate an entrainment cycle is stored.
