In order to make direct performance comparisons of varying the vaneless space in high-speed micro turbomachinery, an extensive experimental and numerical program have been carried out on a 22 mm leading-edge diameter mixed and inward flow radial turbine using a variety of stator designs.
The parameters under evaluation included fabrication and installation method, embedment length, smoothing of the hole edge, hole diameter and dowel angle.
The disk plow employs round, concave disks of hardened steel, sharpened and sometimes serrated on the edge, with diameters ranging from 20 to 38 inches (50 to 95 centimetres).
Theorem 2LetG ( ≇ K | G | ) be a connected graph of order | G |, ∥ G ∥ edges and diameter D ( G ). Then H ( G ) ≥ ∥ G ∥ + ( | G | ( | G | − 1 ) 2 − ∥ G ∥ ) 2 W ( G ) − ∥ G ∥. with equality holding if and only ifGis isomorphic to a graph of diameter 2.
Corollary 1LetG ( ≇ K | G | ) be a connected graph of order | G |, ∥ G ∥ edges and diameter D ( G ). Then H 1 ( G ) ≥ ∥ G ∥ 2 + ( | G | ( | G | − 1 ) 2 − ∥ G ∥ ) 2 W ( G ) − 2 ∥ G ∥ + | G | ( | G | − 1 ) 2. with equality holding if and only ifGis isomorphic to a graph of diameter 2.
The transition from unicellular to multicellular eukarya is associated with a larger NIP (as shown by the increased number of vertices and edges, increased diameter, average network distance, and average node distance, respectively) with more central pathways (as shown by the increased weighted betweenness centrality).
In pin bearing, the limit width-to-diameter and edge distance-to-diameter ratios necessary to avoid unsafe failure modes were lower than those usually quoted for classical laminates.
This work is aimed at providing a new joining technology for C/SiC composites and investigating the influence of drilling holes, hole distribution (including ratios of edge distance to diameter (E/D), width to diameter (W/D) and hole distance to diameter (H/D)) and the number of applied pins on the mechanical properties of C/SiC substrates and joints.
The influences of hole parameters including ratios of edge distance to diameter (E/D), width to diameter (W/D) and hole distance to diameter (H/D), on the mechanical properties of C/SiC substrates were studied by theoretical simulation and experimental methods.
They are useful mostly for accurate visualization of a dendrite connected to the large diameter edge of a soma that happens to be far from the soma centroid.
