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
Flow measurement flow over the bluff body, and formula_17 is the Strouhal number, which is essentially a constant for a given body shape within its operating limits. Sonar flow meters are non-intrusive clamp on devices that measure flow in pipes conveying slurries, corrosive fluids, multiphase fluids and flows where insertion type flow meters are not desired. Sonar flow meters have been widely adopted in mining, metals processing, and upstream oil and gas industries where traditional technologies have certain limitations due to their tolerance to various flow regimes and turn down ratios. Sonar flow meters have the capacity of measuring the velocity of
