[USPRwire, Thu Sep 27 2018] Auto keratometer, or an autorefractor keratometer, is a device used for the measurement of cornea anterior surface curvature across a fixed
chord length. An auto keratometer provides central and peripheral curvatures of the cornea at different points and is used for measurement of astigmatism.
[ClickPress, Wed Sep 26 2018] Auto keratometer, or an autorefractor keratometer, is a device used for the measurement of cornea anterior surface curvature across a fixed
chord length. An auto keratometer provides central and peripheral curvatures of the cornea at different points and is used for measurement of astigmatism.
The cross-sectional airfoil of the wing is NACA4412, and the
chord length of the airfoil was 150 mm and the span of the wing was 600 mm, as shown in Fig.
The body forces acting on the rotor blades are computed on an element of differential size dv = rdrd[theta]dz by using the Blade Element approach as it is shown in (2), where [C.sub.l] and [C.sub.D] are the lift and drag coefficients respectively, c is the
chord length, and [e.sub.L] and [e.sub.D] denote the unit vectors in the directions of lift and drag.
The airfoil is DAE51, and the Reynolds number and angle of attack are [10.sup.5] and 0[degrees], respectively (
chord length 0.2 m).
However, as time evolves, rates of particle breakage and coalescence approach a kinetic equilibrium condition, which causes the stabilization of the number of droplets and of the average
chord length. The characteristic time-length to reach the kinetic equilibrium stage depends on the analyzed operation conditions, including the surfactant concentration, the dispersed phase fraction and the agitation speed.
