The erosion rate according to [3,32] is expressed as: (25) where: 𝜌 𝑤 is the density of target material (kg/m 3 ). 𝐻 𝑣 is Vickers hardness of target material (GPa).…”

“…Al-Baghdadi et al [2] developed a 3-D Computational Fluid Dynamics (CFD) model to describe the turbulent transport of sand particles and crude oil through elbows to estimate erosion rate. Al-Khayat et al [3] studied the erosion due to 3-D flow of crude oil in elbow using CFD. The friction forces between crude oil or sand particles and pipe wall, fluid viscosity, temperature, density and mass flow rate has been studied in the model and well agreed with previously published results.…”

The steady 3-D raw water turbulent flow is numerically investigated. This flow is formed of solid silica sand (quartz) carried by water in stainless steel pipe. The flow in a straight pipe and flow in a pipe with a sudden contraction are analyzed using a two-way coupled Eulerian-Lagrangian approach. Erosion rate is estimated by Oka erosion model combined with the constant coefficient of restitution. The effect of solid particles mass flow rate, inlet velocity, particle diameter, internal pipe diameter, orientation, contraction coefficient, and wall pipe contraction angle on erosion rate are examined. The predicted erosion is distributed homogenously for straight pipe, while the step wall area of the contraction is the most eroded part. The erosion rate increases with the increase of solid particles diameter, flow rate, inlet velocity, and decreasing pipe diameter. Iit is found that the erosion is limited till the particle diameter reaches 500 µm then it starts to increase. The erosion rate increases with decreasing contraction coefficient and step wall angle. When the step wall angle decreased to 300, the erosion rate is reduced by 30 times that for 900. So, decreasing step wall angle can be considered as a geometrical solution to reduce erosion rate.

Three dimensional fluid-thermal-structure multiphysics interaction simulation model of aluminium extrusion process has been simulated and presented in this paper. This multiphysics complex geometrical engineering process is simulated effectively using computational fluid dynamics (CFD) simulation with very high accuracy, where the aluminium material is treated as a fluid that has a very high viscosity which depends on temperature and velocity. When aluminium moving, the inner friction will work as a heat source, therefore the model of the heat transfer is completely coupled together with those governing model of the fluid dynamics. Material properties come into a viscosity function that can be related to the flow stress locally depending on forming velocity and temperature. In addition, the stresses distribution in the die that introduces due to the fluid pressure and the thermal loads has been modelled by fully coupled the simulation model with the structural mechanic's analysis. Fully three-dimensional results during the process of the temperature distribution, velocity profile, von Mises stress distribution, total displacement and deflection distribution, equivalent volumetric strain distribution, and pressure distribution are presented and analysed with a focus on the fundamental understanding. The model is shown to be able to provide a computer-aided design tool for optimize this complex engineering process by improving productivity and reducing scrap.

“…The buckling load of honeycomb sandwich structure with various honeycomb size effect is evaluated by using finite element method with using Ansys program, using the numerical technique. Thus, the finite element method needs to select the element types for problem application, [44][45][46][47][48], therefore, to evaluate the buckling load of honeycomb structure a SOLID 168, 3-D, 10-node, dynamic element must be selected. Since, the honeycomb structure is orthotropic structure, and then, since its element solving the behavior of this structure so that it was selected.…”

The applications of honeycomb structure plate are very important, since its structure have high strength in addition to the low weight. Therefore, these structures are used in the multi-important application, where, more its application is applied to buckling load in addition to other loads. Thus, it was necessary to highlight the buckling behavior of its structure. There, in this research, a suggested analytical solution to evaluate the critical buckling load of honeycomb sandwich plate structure combined from honeycomb part and upper and lower sheet plate parts. Then, the included , by using finite element method, ANSYS program Ver. 15, for various honeycombs core size effect. Therefore, a compare between the results were evaluated analytically and numerically of buckling load are presented to show the agreement between the two techniques were used. Where, the comparison of the analytical and numerical results showed a good agreement of results with a maximum error about (2.24%). Finally, the results showed that the buckling load is modified by increasing the honeycomb core size. There, the upper and lower sheet plate could be used as metal or non-metal materials, [2]. Also, the honeycomb sandwich structure can be made from various materials types as metal, ceramic, composite materials etc. The application of honeycomb structure in engineering leads to supply different loads on the plate. There, one of these loads are the compression load, then, the compression load causes a production of linear elastic deformation of plate structure due to bending behavior of plate. Then, by increasing the compression load on the sandwich plate structure a buckling load is produced on the plate and then a production of bending behavior on it will be shown [3]. results evaluated the mechanical properties of honeycomb part by analytical investigation and buckling load of sandwich plate structure with various parameters effect by the analytical and numerical investigation. The analytical work included the evaluation of the buckling load of a simply supported plate by driving the general equation of buckling the orthotropic plate with buckling load in an x-direction. Also, the results of simply supported honeycombs plate structure were evaluated by the numerical investigationMany studies were presented on the honeycomb sandwich such as mechanical properties, bending behavior, vibration and other behavior of beam or plate honeycomb sandwich with various techniques are
