An efficient numerical model had been developed to model the thermal behaviour
of the rolling process. An Eulerian formulation was employed to minimize the number of grid
points required. The model is capable to calculate the temperature distribution, the heat penetration depth, the convection heat transfer coefficient of cooling, the flow of metal through the roll gap, and the heat generation by plastic deformation and friction. The roll is assumed to rotate at constant speed, and the temperature variations are assumed to be cyclically steady state and localized with a very thin layer near the surface. The Conventional Finite Difference (CFDM) based on cylindrical coordinates was used to model the roll, and a Generalized Fin

Thermal performance of closed wet cooling tower has been investigated experimentally and theoretically

   Surge and swab pressures are frequently produced during various stages of well construction, including casing running and tripping operations. Managing downhole pressure within the mud window is crucial for mitigating the risks associated with drilling operations including wellbore failure, lost circulation, kicks, and well control issues. The primary objectives of this study are to emphasize the theoretical foundation of surge and swab pressures, forecast the optimum pipe and casing tripping speeds, as well as identify the changes in surge and swab pressures (i.e., equivalent circulating density-ECD) for both open-ended and close-ended drill strings. To achieve these goals, a steady state surge and swab model was used to simulate a

A numerical investigation has been carried out to examine the effects of insulated baffle mounted in complex cavity representing as an industrial building on flow pattern and heat transfer characteristics. The cavity is formed by adiabatic horizontal bottom, inclined upper walls and vertical isothermal walls. This problem is solved by using flow-energy equations in terms of stream-vorticity formulation in curvilinear coordinates. Two cases are considered; in the first (case 1) the insulated baffle position attached to the horizontal bottom wall of the cavity while in the second case (case 2) the insulated baffle position attached the upper inclined wall. A parametric study is carried out using following parameters: Rayleigh number from 1

In the present study, a nonlinear three-dimensional finite element analysis has been used to predict the load-deflection and moment-rotation behaviors of composite encased beams consisting of preflex steel sections using the finite element computer program (ANSYS V. 10). Composite encased beams are analyzed and a comparison is made with available experimental moment-rotation curves, good agreement with the experimental results is observed. Camber of steel section is introduced on the steel section of the composite beams encased in concrete. It is found that using of preflex section can increase the ultimate load capacity of the composite encased beam by relatively (15%) and also it is found that rotations are nearly (65% to 80%) the rota

This study focuses on the slab-beam interaction in one-way systems. In the context of this study, slab-beam interaction means how beam deflection can affect moment distribution in one-way slabs. This interaction is usually neglected in the traditional approximate analysis that is adopted in engineering practice and design codes. Slab positive moments have been considered as indicators on the accuracy of approximate methods, as they overestimate negative moments while underestimating positive moments.

After proposing of effecting parameters in slab-beam interaction including of panel length and width, beam dimensions, and slab thickness, Buckingham’s  theorem has been adopted to transform the dimensional-mo

One of the most important techniques for preparing nanoparticle material is Pulsed Laser Ablation in Liquid technique (PLAL). Carbon nanoparticles were prepared using PLAL, and the carbon target was immersed in Ultrapure water (UPW) then irradiated with Q-switched Nd:YAG laser (1064 nm) and six ns pulse duration. In this process, an Nd:YAG laser beam was focused near the carbon surface. Nanoparticles synthesized using laser irradiation were studied by observing the effects of varying incident laser pulse intensities (250, 500, 750, 1000) mJ on the particle size (20.52, 36.97, 48.72, and 61.53) nm, respectively. In addition, nanoparticles were characterized by means of the Atomic Force Microscopy (AFM) test, pH easurement
