Modelling of surface formation mechanism during burnishing of aluminium

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Dynamic modelling of hardness changes of aluminium nanostructure during mechanical ball milling process

In this research, the feasibility of using mathematical modelling in the ball milling process has been evaluated to verify the hardness changes of an aluminium nanostructure. Considering the model of normal force displacement (NFD), the radius of elastic-plastic and normal displacement of two balls were computed by applying analytical modelling and coding in MATLAB. Properties of balls and alum...

Roller Burnishing of Particle Reinforced Aluminium Matrix Composites

Energy and resource efficient systems often demand the use of light-weight materials with a specific combination of properties. However, these requirements usually cannot be achieved with homogeneous materials. Consequently, composites enabling tailored properties gain more and more importance. A special kind of these materials is aluminium matrix composites (AMCs), which offer elevated strengt...

Formation Mechanism and Enthalpy of Mixing of Nanocrystalline NiTi Intermetallic during Mechanical Alloying

Mechanism Analysis of Free-Surface Vortex Formation during Steel Teeming

To develop an effective technology to prevent vortex forming in ladles, the mechanism underlying vortex formation during steel teeming must be studied. For simulations using the numerical simulation software Fluent, a geometric model of the ladle was generated, and initially water teeming in the ladle was simulated for different initial tangential velocities. The results obtained help to verify...
