Abstract: Flow drag reduction with polymer additives has been studied and applied for many years. But degradation of the drag-reducing agent (DRA) is still not well understood. In this study, a new theory for the mechanism… read more here.

DOI: 10.1021/acsomega.3c01841
Abstract: In the continuous liquid distribution process, the emulsion drag-reducing agent has poor viscosity-increasing ability and a low solid content, resulting in a high concentration and high cost. To solve this problem, a nanosuspension agent with… read more here.

DOI: 10.3390/polym11101659
Abstract: Viscoelasticity drag-reducing flow by polymer solution can reduce pumping energy of pipe flow significantly. One of the simulation manners is direct numerical simulation (DNS). However, the computational time is too long to accept in engineering.… read more here.
