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 ...

The objective of the paper is the assessment of the wind load applied to a real photovoltaic (PV) platform installed on a site situated in Brasov, which belongs to the Transilvania University. The platform has a double-tracking axis mechanism which allows the rotation of the platform disk depending on the sun position, in order to gather the maximum solar yield to produce electricity. The study ...

This paper presents some results of numerical simulations carried out to investigate the basic hydrodynamic interactions between the laminar flow in the water column above triangular bedforms and the Darcian flow in the underlying permeable sediments. The flow was described by the Navier-Stokes equation in the free region and the Darcy equation in the porous region. Numerical simulations were ...

We present here our work on deconvolution of a magnetic probe to mesure electromagnetic emissions in near-field zone. To achieve this work,we have chosen a rectangular waveguide (WR90) as a radiating structure.Theoritical near-field is simulated using a FEM software (COMSOL) and also obtained by using a program based on transverse operator method (TOM), that lead to a very good field ...

A compacted bentonite clay buffer is planned to be used as a part of the engineered barrier system in the KBS-3 concept for the disposal of spent nuclear fuel. Simulations together with experimental studies are needed to ensure that bentonite fulfills its safety functions in the concept. In this paper, one type of bentonite model, namely a thermomechanical model developed by Jussila, is presented ...

In the inspection of steel products with respect to flaws a magnetic flux leakage (MFL) test procedure can be applied. In this procedure a “horseshoe” shaped yoke is used, whose legs are wrapped with coils through which an alternate current with a high frequency (3 kHz) is flowing. Hereby a thin magnetic field is induced near the surface of the test object which leaks from the material if a ...

Anders B Nilsson graduated M. Sc. in engineering physics from Lund University in Sweden. He has been working in the R&D department at BD Medical as principal engineer and project leader since 2005. He uses COMSOL for a wide range of functions, such as early concept development and qualification of products.
The developments of microsystems for biotechnology have been fast in the last few years, and no sign of slowing down is observed. It has begun with lab-on-chip for genomics, especially for the recognition of DNA sequences, followed by protein reactors and immunoassays, and today the emphasis is on cellomics. Cell-chips are design to monitor the behavior of cells, individually or as a group, ...

For the numeric investigations of the high temperature compact heat exchanger two numeric models with and without the regards of the velocity field development were used. The results of the comparison of the numeric and experimental data confirm the necessity of regarding the velocity field development for the compact heat exchangers. The two-dimensional simulation task with the regard of ...
