Shear flow themselves. In a shearing flow, adjacent layers of fluid move parallel to each other with different speeds. Viscous fluids resist this shearing motion. For a Newtonian fluid, the stress exerted by the fluid in resistance to the shear is proportional to the strain rate or shear rate. A simple example of a shear flow is Couette flow, in which a fluid is trapped between two large parallel plates, and one plate is moved with some relative velocity to the other. Here, the strain rate is simply the relative velocity divided by the distance between the plates. Shear flows in fluids
Physics of Fluids of 2.279. Physics of Fluids Physics of Fluids is a peer-reviewed monthly scientific journal on fluid dynamics, founded by the American Institute of Physics in 1958, and is published by the AIP Publishing. The journal focus is the dynamics of gases, liquids, and complex or multiphase fluids—and the journal contains original research resulting from theoretical, computational, and experimental studies. From 1958 through 1988, the journal included plasma physics. From 1989 until 1993, the journal split into "Physics of Fluids A" covering fluid dynamics, and "Physics of Fluids B," on plasma physics. In 1994, the latter was renamed "Physics of Plasmas",
