The use of high power microwave energy for ablation of contaminated concrete is a promising technique to speed up the dismantling of nuclear power plants. A coupled simulation using COMSOL Multiphysics® finite element software is performed by solving the electromagnetic wave equation at 2.45 GHz for a standard wave guide and a concrete block. The temperature field is obtained with the heat ...

This study is to investigate the velocity pattern and the velocity magnitude of the cuttings that is being processed in the process mill as a result of the rotating hammers. The process mill consists of a horizontal cylindrical shell equipped with renewable liners and rotating hammers for milling of drill cuttings. An F.E model of the process mill was constructed using dimensions similar to ...

The high flow rate within the HFIR cooling water flow channel causes the fuel plates to deflect which in turn, changes the coolant flow characteristics. This nonlinear feedback loop between the coolant and the fuel plate is the focus of the present simulation of the fluid-solid interaction between the coolant flow and the fuel plates to accurately predict the plate’s deflection using the Fluid ...

Describing and predicting the extent of the physicochemical processes as well as geometrical deformation taking place during food transformation is of major importance to control food functional properties. Unfortunately, only a few food-matrix models consider deformation particularly because of large deformation. In the case of a starchy product such as rice, water transport and swelling ...

Predicting the physical properties and performance of carbon and graphite materials based on the microstructure of the finished material is a challenging endeavor. This paper discusses the process and workflow for measuring and analyzing the pore structure of graphite by combining advanced CT image technology with Simpleware’s ScanIP™ software. A stack of scanned CT images are imported into ...

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded contacts the effects are currently in basic research. Elastic deformation in the contact area plays an important ...

Adaptive Optics is common sense, since many people use digital cameras with electromechanical iris actors on elastic autofocus lenses. This project tries to create a COMSOL Multiphysics based mathematical model of adaptive optics with electrostatically induced deformation of dielectric gels. Upper and lower sides of a lens (dielectric conductive gel) are coated by transparent conductive films, i ...

This paper presents a numerical analysis of indented pipes based on the Finite Element (FE) within the framework of COMSOL Multiphysics. Numerical models using two-dimensional solid plane strain elements are evaluated. Geometric nonlinear analysis, nonlinear isotropic hardening material and contact were also incorporated into the models. The numerical models are calibrated by using an ...
The safety of large civil structures is often evaluated by means of numerical models based on the Finite Element Method. In this frame, the choice of a constitutive law able to represent the complex mechanical behaviour of concrete is a key point. This paper deals with a detail description of all the steps needed to implement the Microplane Model in COMSOL; the formulation is based on the ...
