  • Effect of micro-channel geometry on fluid flow and mixing ...

    2011-4-1 · Geometry 1 is poor for mixing and there was nothing to encourage mixing in the fluids that flow through it. In microchannel Reynolds number ( Re ) is calculated as Re = ( LV avg ρ )/ μ, where L is the effective channel length, V avg is the average velocity of fluid in the channel, ρ is the density and μ is the viscosity of the fluid.

  • Effects of Focus Geometry on the Hard Rock-Cutting ...

    Abrasive waterjets are being increasingly used in civil engineering for rock and concrete cutting, particularly for the demolition or repair of old structures. The energy of an abrasive waterjet is primarily provided by the accelerated abrasive. The momentum transfer during mixing and acceleration determines the abrasive velocity, which affects the cutting performance.

    2008-1-1 · Therefore, for lower distances between the light guide and the restorative material, the tip with a higher R-value is more efficient. Between 4 mm and 5 mm of distance, there is a change in efficacy between the two tips, and the tip with R=1.18 generates a higher depth of cure (4.52 ± 0.02 mm) than the tip with R=1.63 (4.44 ± 0.03 mm).
