One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. In this work, we consider a simple model for air injection in light oil reservoir containing only one component in dry ...

The paper presents recent results concerning the experimental mechanical characterization, the numerical modeling and the design of micro-needles used in the construction of probe heads for wafer testing. A fully coupled electro-thermal model was created using COMSOL and combined to a research-oriented thermo-mechanical Finite Element (FE) code in order to accurately reproduce the micro-needle ...

Spondylolysis (SL) is a defect of the spinal vertebra, and is typically caused by stress fracture of the pars interarticularis bone of the vertebral arch. It is especially common in adolescents who over train in sporting activities. Spina bifida occulta (SBO) is a malformation of the spine where the protruding vertebral bodies are not fully formed. In this study we demonstrate the predisposition ...

This work focuses on the application of multiphysics finite element simulations in the manufacturing and application of high power ultrasonic machines. Industries providing big power ultrasonic solutions as in cleaning, welding, sonochemistry and cutting fields, already apply the finite element simulation approach, in the structural mechanics flavor, in the design and optimization of ultrasonic ...

COMSOL Multiphysics has been used to validate and check the design of a header transporting ammonia gases released from pressure safety valves (PSVs) to the tip of the flare. The header is part of a dedicated flaring system to contain emissions from ammonia storage tanks. The two main challenges are the low relief pressure and high capacity of the system. Another difficulty is the high relief ...

Introduction: The chemical properties of the heaviest elements (atomic number Z > 103) depend on the influence of the high nuclear charge to their electronic structure. Enhanced chemical stability of copernicium (Cn, Z = 112) and flerovium (Fl, Z = 114) was predicted already 40 year ago by Pitzer . The challenge of chemical investigations of these elements is the tiny production rates of few ...

This paper presents a successful step towards the development of a “web-based laboratory” for teaching basic, and even advanced, electromagnetic concepts. The main idea is to develop a reusable model for the student to be used exactly as a hardware experiment in a physical laboratory, where he/she can change some of the experiment\'s physical parameters and get corresponding results. The two ...

Most of mining works, either on the surface or in the underground, demand continuous groundwater pumping in order to operate under dry conditions. When the mining activity stops, dewatering also stops and mining facilities begin to flood, quite quickly at the beginning but becoming slower as the water level in the pit lake rises. The rise of the surface of the lake decelerates due to the bigger ...

The Swedish Organization for Radioactive Waste (SKB) is considering disposal High Level Wastes in a deep underground repository. Bentonite clay is planned to be used in the near-field of the waste packages as buffer material. The buffer is expected to provide a favorable environment with limited radionuclide migration due to slow diffusion and retardation by sorption and cation-exchange effects. ...

Simulations of more than one type of seal have been done where the deformation and the stress of the seal itself or the pressure on the housing are of interest. According to the deformation of the seal we can modify the housing of the seal or its geometry depending on the design constraints to meet. Stresses on the seal are indicators of which changes have to be implemented on the geometry so to ...
