A novel test methodology is established to evaluate the strain relief boot on optoelectronic components and optical fiber components by measuring the fiber bend radius in side pull test. The technique is developed for qualifying the boot design rather than for lot testing. The criterion and process are provided.

this paper presents a numerical study of local mass transfer coefficients in a 90° bend using the rng version of k–e model to include the influence of curvature on the turbulent transport. simulations were performed for flow through a 90°, 3-d bend for reynolds numbers of 13500, 90000, and 390000, schmidt numbers of 2.53 and 700 and curvature ratios of 1.5, 2, and 2.5. the differences between t...

In the present research, the laminar forced convective heat transfer and fluid flow characteristics for Al2O3-water nanofluid flowing in different bend (i.e., 180o and 90o) pipes have been investigated numerically in a three-dimensional computational domain using the finite volume technique. The effects of different pertinent parameters, such as the Reynolds number of the duct, volume fraction ...

In this paper a new method of microwave nondestructive testing based on electromagnetic guided waves is applied to detect circumferential crack in the piping system of nuclear power plants. Microwaves as continues wave are generated by a network analyzer and amplitude of the reflection coefficient is measured by this network. For detection of any type of crack with any orientation in the pipe, ...

Polycrystalline yttrium aluminum garnet (YAG) fibers were prepared from commercially available colloidal sols of Y,O, and AlOOH and water-soluble polymers. The fibers were dry spun and all processing was performed in air. Transformation to YAG was complete by =1300"C, and the fibers were mostly dense by 1600°C with a final fired diameter of 120 pm. A bend test was used to characterize mechanica...
