A 3D thermo-mechanical simulation was developed using COMSOL Multiphysics software in order to predict distortion of a welded dissimilar titanium alloys structure. An angular distortion and a longitudinal shrinkage are predicted in agreement with those obtained experimentally.

The Levant has been repeatedly devastated by numerous earthquakes since prehistorical times. In order to understand the role of the dynamics of the water bodies in triggering the deformations in the Levant basin, a new theoretical thermo-mechanical model is constructed and extended by including a fluid flow component, in COMSOL Multiphysics simulation environment. The latter is modeled on a ...

This paper introduces an efficient model to describe energy dissipation in acoustic. When the propagation domain has hard wall boundary conditions only viscous and thermal losses happen and are completely described by the so-called Full Linearized Navier-Stokes model (FLNS) which is implemented in thermoacoutics interface using the COMSOL Acoustics Module. This model defined by a set of ...

Studies of the liquid metal movement (hydrodynamic) in a real object (tundish) are substantially precluded due to the objective difficulties (high temperature and the size of metallurgical equipment), compared to their execution by the use of physical and numerical modeling. In presented study, two test methods for analyzing the flow and mixing of the liquid steel in the tundish were used. The ...

Photosynthesis can be defined as the conversion of solar energy into chemical energy. In green plants, this applies to the conversion of CO2 into organic compounds. The energy stored in these compounds can later be used to supply energy to run physical and chemical processes in plant cells. Since photosynthesis allows crops to maintain themselves and to grow , it is of great importance for ...

The UK Advanced Gas-cooled Reactor fleet, operated by EDF Energy, utilize a graphite core consisting of a lattice of around 3000 annular bricks. Due to irradiation, oxidation and thermal effects, the bricks deform and loose mass as they age. Of key concern is the late-life behavior of the bricks, in particular the predicted time at which brick shrinkage reverses into expansion, generating large ...

Radioactive waste repositories include barriers that work to contain the waste, thereby protecting human health and the environment. In deep geological disposal systems, barriers include the natural geological barrier and the engineered barrier system (EBS). The ability of the EBS to limit groundwater flow is important and optimized design solutions are often sought by means of numerical ...

Unmanned aerial vehicles (UAVs) have recently received great interest due to their great potential in both military and civil applications [1-4]. Testing and construction of UAVs is expensive and time consuming and a simulation approach can help to reduce cost for both design and tests. In this paper, the authors have used COMSOL Multiphysics software to design a UAV’s pod equipped with a Solid ...

Resistive heating filaments used in high temperature applications at 2000°C and above are often made of refractory metals. The lifetime of such filaments is mainly limited by creep deformations which can in the worst case lead to a short circuit between filaments and other furnace components. With the aid of COMSOL Multiphysics software, the time-dependent creep deformation behavior of a heater ...
