The main purpose of this study is to perform numerical simulation of nanofluids as the coolant in VVER-440 fuel rod bundle. The fuel rod bundle contains 60 fuel rods with length of 960 mm and 4 spacer grids. In VVER-440 fuel rod bundle the coolant fluid (water) is in high pressure and temperature condition. In the present Thermo-hydraulic simulation, water-AL2O3 nanofluids containing various vo...
In the present work, first an analytic relation for position-dependent effective mass in a quantum rod is obtained. Then, the effect of position-dependent effective mass on the intersubband optical absorption coeffcient and the refractive index change in the quantum rod is examined. Our numerical calculations are performed using both a constant effective mass and the position-dependent effect...
In this paper by analyzing the penetration mechanics of the segmented rods into semi-infinite ceramic targets, a mathematical model is provided to predict segmented rod projectiles penetration into semi-infinite ceramic targets. In analysis three factors of segments length, segments distance and number of segments are considered. Results suggest that the most important factor in penetration dep...
Process tolerancing based on the process capability studies is the optimistic and pragmatic approach of determining the manufacturing process tolerances. On adopting the define–measure–analyze–improve–control approach, the process potential capability index (C p) and the process performance capability index (C pk) values of identified process characteristics of connecting rod ...

in this research, a braiding-pultrusion production line is developed by modifying a conventional textile maypole braiding machine and adding it to a pultrusion line for production of braid-pultruded (bp) composite rods. in order to evaluate the mechanical properties of bp rods and study the effect of some braiding parameters, they were produced with different braid roving linear densities and b...
background chronic hepatitis c virus (hcv) is associated with extra hepatic autoimmune disorders, while peg-ifna-2a/rbv combination therapy may exacerbate these conditions. autoantibodies to cytoplasmic structures, called rod and ring particles (rr), have strong associations with these patients and are identified by hep-2 cells. objectives our purpose was to study the correlation of autoantibod...
STUDY DESIGN Three types of anterior thoracolumbar multisegmental fixation were biomechanically compared in construct stiffness and rod-screw strain. OBJECTIVES To investigate the effects of rod diameter and rod number on construct stiffness and rod-screw strain in anterior thoracolumbar multisegmental instrumentation. SUMMARY OF BACKGROUND DATA No studies have been undertaken to investigat...
the coordinate transformation allows the exact calculation of some electrode configurations. in this paper the prolate spherical coordination transformation is used to calculate the field of a hyperboloiderod against plan electrode. the exact field is caculated using two new parameters: 1) electrodes spacing and 2) the radius of curvature of the tip of the rod electrode. the partial discharge i...
