“…AutoCAD was used to design the pipeline and grid. Because of the hexahedral mesh's ability to deliver better solutions with fewer cells, geometry has been adopted [27]. Meshed models were used in this study, as shown in Fig.…”

In this study, computational analysis has been carried out using computational fluid dynamics (CFD). These calculations have been made to investigate the rheological behavior of the mixed-phase flow in horizontal pipelines. In order to study the shear stress in a vertical pipe, a new numerical model for oil-water dispersion in three dimensions has been developed. CFD software has been used to study the wall shear stress function and water droplet pressure. Using Reynolds numbers and the Navier-Stokes equations with k–turbulence factor to save energy, the flow range for the continuous process was explained. The results from a recent study on experimental methodology were simulated. In this study, the diameter of the tube is 40 mm and the length is 3.5 m and modeled and analyzed using Ansys software. Thus, the geometry has been imported and modeled using the CFD tool. The meshed model has been tested and converged accordingly. The primary data of the simulation have been verified with experimental results successfully. Oil droplet widths have previously been thought to be dependent on the flow Reynolds number, which was confirmed in this case study. Droplet diameter Dd was measured at 6 mm while the mixture moved at a speed of 1.9 m/s. It was found that the largest shear stress value was found at the top of the pipe, where the oil fraction (cut-off) was 0.3, in the simulation results for varied velocities (1.6, 2.5, 2.9 m/s) and oil fraction (cut-off) values. The results of the simulation analysis of the two-phase flow of crude oil for the horizontal pipe are wall shear stresses with different velocities for crude oil in the two-phase flow. As well as pressure drop at different velocities for the same fluids

“…Thermal plasmas are widely used for the synthesis of nanomaterials [1][2][3], arc welding, cutting of metallic materials by plasma torch [4], plasma spraying [5], high and medium voltage circuit breakers [6], arc furnaces in metallurgy, high pressure lamps or vitrification and waste treatment [7]. Consequently, they are the subject of numerous research studies aiming to gain a better understanding of them and to anticipate the physical process that they generate.…”

In order to control flows and temperature distribution within plasma reactors experimentally requires significant research and development costs. the computational fluid dynamics (CFD) can be used as a powerful tool to investigate the flow pattern and heat transfer inside plasma reactors allowing us to construct best designs with minimal cost. In this work temperature profile and gas flow distribution in the thermal plasma reactor used for carbon nanotubes synthesis is studied by COMSOL Multiphysics. Two background gases Helium (He) and Nitrogen (N2) was compared. We conclude that unlike Nitrogen, Helium ensures a good recirculation in the arc chamber and therefore a good replenishment of the atmosphere by the reactants during the process.
