A beneficial method for transporting highly viscous hydrocarbons (e.g. heavy oil and bitumen) through a pipeline is known as Lubricated Pipe Flow (LPF). A major challenge for this technology is flow instability caused by the formation of a wall-coating of oil or the thinning and/or loss of the lubricating water layer in the pipe. This issue can be addressed by using capacitance sensors to measure ...

The Huygens Atmospheric Structure Instrument (HASI) was designed to characterize the physical properties of the lower atmosphere and surface of Titan, the planet-size moon of Saturn. The Relaxation Probe (RP) sensor on the Huygens probe, determined the electrical conductivity in the lower atmosphere of Titan, from 140 km to 40 km. It was suspected that at an altitude above 100km, the booms ...

This paper presents an analysis approach of multicondcutor quasi-TEM lines transmission interconnect in a single dielectric region and multimode waveguides using the finite element method (FEM). FEM is especially suitable and effective for the computation of electromagnetic fields in strongly inhomogeneous media. We illustrate that FEM is suitable and effective as other methods for modeling of ...

The concept of virtual prototyping can be found linked to many different keywords in the literature: modeling, look-ahead problem solving, etc. This poster paper briefly discusses the potential real benefits that can be realized through pre-build cost savings, minimization of the number of prototype builds, and post-build problem avoidance for physical prototypes and production products. Relative ...

Technological processes in the engineering practice from point of view of systems and control theory are frequently in the form of distributed parameter systems (DPS). Techniques of FEM based modeling and design of control synthesis methods of DPS which is acceptable for various technological processes, will be demonstrated on modeling and control of temperature fields of the glass melting ...

Modernization of the High Flux Isotope Reactor (HFIR) thermal-hydraulic (TH) design and safety analysis capability is an important step in preparation for the conversion of the HFIR core from a high enriched Uranium (HEU) fuel to a low enriched Uranium (LEU) fuel. Currently, an important part of the HFIR TH analysis is based on the legacy Steady State Heat Transfer Code (SSHTC). The SSHTC is a ...

In order to investigate the implantation of microprobes into brain tissue, we developed a finite-element and a physical model to replace real biological tissue for mechanical testing. Penetrating forces of a tungsten indenter into a layered structure was investigated with different indentation speeds. Numerical and physical model are in good correspondence to each other and reproduce measured ...

The study presents first authors experience with COMSOL Multiphysics environment used as a possible modeling tool of thermal building behavior. The idea of the project was to gain thermal response to changed boundary conditions with the application of COMSOL environment as a modeling tool for 3D buildings or 3D building segments. The room as building segment was implemented in the COMSOL ...

The contact between infinitely rigid body and deformable part is studied using the velocity as a dependent variable. A simple forging case is evaluated. The velocity approach is realized by means of using COMSOL with the Equation-Based Modeling. The contact model evaluated in this work is suitable to model the forging process. For a given mesh and element it is possible to choose the optimum ...
