In this work we want to explore some techniques, microfluidic and electrospray-ionization based, suitable for dynamic microarrays\' fabrication. The fabrication techniques are based on manipulation and self-assembly of selective coated micro and nanobeads. The simulation will include electro-osmotic flow, species transport, and electrostatics.

Simulation tools for building physics problems play an important role in design and understanding the behavior of energy efficient buildings. There are different tools available for simulation of these problems, but each simulation tool has its own advantages and limitations. In this paper, a heat transfer problem in an exterior building wall with high performance materials has been simulated in ...

In this paper, we present a first model carried out with COMSOL Multiphysics to model bread baking, considering heat and mass transfer coupled with the phenomenon of swelling. This model predicts the pressures, temperatures and water contents evolutions in the dough for different energy requests. First results obtained are analyzed according to various physical parameters in order to better ...

Powder metallurgy is a key technology for manufacturing advanced components based on TiAl alloys. Cold compaction is the primary step to produce green parts. Cold deformation of TiAl powder is difficult due to its typical poor ductility. Plastic deformation and cracking susceptibility of TiAl powder strongly depends on micro-mechanical phenomena. To manage real compaction problems more reliable ...

The present study relates to the reduction of the amount of air to gas leakage in a typical rotary regenerative air preheater of coal-fired steam generators, by means of computational thermo-fluid-dynamics. Due to the gaps, or clearances, required for rotation, there is a significant amount of leakage of the higher pressure air to the lower pressure gas stream. This paper presents a turbulent CFD ...

We report a numerical study on the blood – magnetic carrier aggregate flow in an external magnetic field, for applications such as magnetic drug targeting. The arterial system morphology is complex and patient-related therefore more realistic numerical simulations request medical image-based reconstruction to generate computational domains. Simpleware package is used to generate the ...

This paper describes consecutive stages of design and construction of electromagnetic gun manufactured at the Silesian University of Technology. It gives insight into current knowledge about such a launcher. The computer model was elaborated in COMSOL Multiphysics version 3.5. The numerical analysis was carried out a 3-dimensional space. The physical model was build up and comparison of the ...

This paper deals with the design of a viable thermal management solution using La5Ca9Cu24O41 layers for heat channeling. The simulations are carried out with the finite element method using COMSOL Multiphysics Heat Transfer Module. COMSOL 4.2 was used to model and optimize silicon devices. Malfunctioning elements on silicon devices are sometimes converted into hotspots resulting in the ...

We deal with Liquid Crystal Elastomers (LCEs) having hybrid alignment (HNEs), that is, fabricated with a given non-homogeneous nematic orientation. For such a materials, permanent distortions induced by deswelling can be compensated by those resulting from cooling below the transition temperature, thus yielding the possibility of producing temperature-driven actuators. Here, we simulate the ...
