This paper deals with the measurement of AC corona inception voltage, Vincp, at the tip of a rod electrode using a hemispherically-capped rod-plane electrode configuration for various rod radii with a short air gap. Effects of atmospheric pressure and temperature variation on Vincp are investigated experimentally. An empirical equation for the field form factors of the hemispherically cappe...

Adaptive and flexible control techniques have recently been examined as methods of controlling flow reducing the potential noise in vertical axis wind turbines. Two-Dimensional (2D) fluid simulation around rod-airfoil is addressed this study a simple component turbine by using Unsteady Reynolds Averaged Navier–Stokes (URANS) equations for prediction Ffowcs Williams-Hawkings (FW-H) analogy. To r...

To evaluate the effect of acupuncture on the severity of withdrawal reaction during rapid opiate detoxification (ROD), forty adult male subjects addicted to opioids and scheduled for ROD by naloxone were randomly divided into acupuncture and control groups. In the acupuncture group during three consecutive days immediately before induction of ROD, body acupuncture was performed while in the con...

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...

The article is related to the field of geodetic and engineering construction monitoring building structures in form rod systems. It investigates measurement accuracy compression deformation rod. As an example, there considered a vertical rectilinear high flexibility, loaded with longitudinal axial force. Experience demonstrates that rod, under influence compressive load not exceeding permissibl...

A square splittered and unsplittered rod is placed in a turbulent boundary layer developed over a flat plate. The effect of the resulting disturbances on the local heat transfer coefficient is then studied. In both cases the square rod modifies the flow structure inside the boundary layer. As a result, a stagnation point, a jet and wake area are generated around the square rod, each making a co...

Nano HA rod was synthesized by precipitation method using Ca(NO3)24H2O and (NH4)2HPO4 as starting materials and ammonia solution as an agent for pH adjustment. The Ca/P molar ratio was maintained at 1.67. Then, the effect of different pH (4, 6, 8, 10, 11), different surfactants and different times for dialyses on nano HA rod were studied in this study. The samples were characterized by differen...
