Polymers Reduce Drag More than Expected - PlasticStar

Adding polymer to a liquid was thought to reduce drag only up to a point, but new experiments have found exceptions to the usual limit. Frictional drag steals energy from a moving fluid, but the loss usually becomes greater as the flow goes from smooth, or “laminar,” to turbulent.

Encapsulated NRGBs are extremely sluggish in reducing fluid viscosity and require very high loadings to achieve results comparable to RGBs. Fluid formulations designed with the correct RGBs, at an optimal concentration, render a steady viscosity decrease and a sufficiently low final viscosity, near that of water, to aid in cleanup and flowback.
