a steady two-dimensional laminar free convection heat transfer from a cold horizontal isothermal cylinder located above an adiabatic floor is studied both experimentally and numerically. in the experimental measurements the effects of cylinder distance from horizontal floor to its diameter (l/d) on heat transfer coefficient is studied for rayleigh numbers of 3×105 and 6×105. computations are ma...
The Tinius Olson Universal Testing machine (see Figure 1.1) is capable of loading a test specimen to a maximum load of 60,000 lb. The load applying section of this machine consists of three thick metal plates. The top and the bottom plates are rigidly connected together with thick tie rods. This assembly is connected on the bottom to a hydraulic cylinder which is contained within the base of th...
Abstract—The present study focused on carrying out the creep analysis in an isotropic thick-walled composite cylindrical pressure vessel composed of aluminum matrix reinforced with silicon-carbide in particulate form. The creep behavior of the composite material has been described by the threshold stress based creep law. The values of stress exponent appearing in the creep law were selected as ...
The Compact Muon Solenoid (CMS) is one of the general-purpose detectors to be provided for the LHC project at CERN. The design field of the CMS superconducting magnet is 4 T, the magnetic length is 12.5 m and the free bore is 6 m. Almost all large indirectly cooled solenoids constructed to date (e.g., Zeus, Aleph, Delphi, Finuda, Babar) comprise Al-alloy mandrels fabricated by welding together ...
In this paper, effects of EHD actuators on hydrodynamic behavior and heat transfer of air flow over a circular cylinder were considered. Pressure and temperature distributions around the cylinder were measured in presence of wire-plate EHD actuators. The Reynolds number based on cylinder diameter (d) were 3500, 7000. Experiments were performed for various configurations. Based on obtained resul...
Abstract The use of lightweight metal cylinders is great significance to artillery weapon systems in terms significant mass reduction, service life extension, power consumption reduction and operational effectiveness. Based on the load conditions provided by classical internal ballistic theory, a high precision finite element model solved explicit integration algorithm with central difference. ...
