No-slip boundary condition is one of the common assumptions in rheological analysis, especially for polymer melt flow in capillary rheometers. In fluid dynamics, this assumption means that at the wall ...

Princeton researchers have solved a 54-year-old puzzle about why certain fluids strangely slow down under pressure when flowing through porous materials, such as soils and sedimentary rocks. The ...

Rheology is the science of studying the flow and deformation of materials rooted in the laws of elasticity and viscosity proposed by Hooke and Newton in the late 17 th Century. Thermoplastic polymer ...
