Summary
A detailed investigation has been undertaken to study the turbulent drag reduction caused by commercial guargum, purified guargum and newly synthesized graft copolymers of guargum, in recirculatory turbulent flow of water. The shear stability of these systems has been studied in the same recirculatory turbulent flow system. The relative performance of these systems for the turbulent drag reducing effectiveness and the shear stability has been explained on the basis of molecular behaviour of drag reducing polymers.
A detailed study has been performed on the percolation of water added with guargum and guargum and carboxymethyl cellulose mixture through a soil column. The prediction equation of polymer added water through soil column have been developed. A molecular interpretation has been put forward for both the phenomena discussed in this paper.
