Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC

The ATLAS detector as installed in its experimental cavern at point 1 at CERN is described in this paper. A brief overview of the expected performance of the detector when the Large Hadron Collider begins operation is also presented.

Numerical investigation of natural convection of cavity receiver for low power application

Generally built in desert areas, heliostat fields undergo various wind loading conditions. An ANSYS Fluent CFD model of an isolated heliostat in worst-case orientation for the drag force is realized via numerical simulations using the realizable k-e turbulence model. This paper focuses on the gap width between the panels and its influence on the wind loading that heliostats are subjected to. An atmospheric boundary layer profile is generated based on a wind tunnel experiment. For a heliostat in upright and tilted orientations with the wind angle being zero degrees, the gap width is varied and the force and moment coefficients are calculated. In the range tested, all the coefficients globally increase with the widening of the gaps.

External surface temperature measurements for the heat transfer analysis of internally heated cylindrical clad-tubes subjected to external forced convection bulk water coolant thermal-hydraulic conditions

In this research for the first time, banana-fibre nanoparticles produced for nanofluid application and the viscosity of resultant nanofluids were measured.A Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM) were used to analyzethe sizes of the particles produced(200nm). This paper presents new findings on the synthesis of natural fibre to obtain nanoparticles and subsequently produced nanofluids. Nanofluids are prepared by dispersing Banana fibrenanoparticles in deionized water.An ultrasonic sonicator was used to ensure proper mixtures of different volume fractions (0.3%, 0.6 %, 0.9 % 1.2 % and 1.5%) of Banana fibre nanoparticles into base fluid (DI water). A Vibro Viscometer machine (SV-10) is used to measure the viscosity of the prepared nanofluids more conveniently. For minimum and maximum volume fractions of Banana fibre-nanoparticles (0.3% and 1.5%) in deionized water,the viscosity was found to be 1.08 mPa.s and 1.23mPa.s, which increases slightly with an increase of particle volume fraction and decreases as the temperature increases.The experimental results show a maximum of 22% increasing of viscosity for 1.5% volume fraction of nanofluids as compared with the deionized water (base fluid). From the experimental study on prepared nanofluids conducted, results show that all the values of viscosities at different volume fractions of the prepared nanofluids were found to be substantially higher than the values of the base fluids (deionized water). The experiments were conducted at varying temperature range (20 o C through 60 o C).
