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
Experiments in Fluids Experiments in Fluids Experiments in Fluids is a scientific, peer-reviewed scientific journal published monthly by Springer Science+Business Media. The journal presents contributions that employ existing experimental techniques to gain an understanding of the underlying flow physics in specific areas. These areas include turbulence, aerodynamics, hydrodynamics, convective heat transfer, combustion, turbomachinery, multi-phase flows, and chemical, biological and geological flows. In addition, papers report on investigations combining experimental and analytical/numerical approaches. The journal also publishes letters and review articles. "Experiments in Fluids" had a 2017 impact factor of 2.195. The editors of the journal are E. K. Longmire (University of Minnesota, USA),
