One of the major challenges in biology concerns the integration of data across length and time scales into a consistent framework: how do macroscopic properties and functionalities arise from the molecular regulatory networks and how do they evolve? A deeper understanding of morphogenesis and organogenesis in particular is required to advance tissue engineering. Recent advancements in 3D ...

In the pool type Fast Breeder Reactors the roof structure is penetrated by a number of pumps and heat exchangers which are cylindrical in shape. Argon gas in reactor is sandwiched between the free surface of sodium and the roof structure and can flow in the annular space between the components and roof structure forming a thermosyphon. These hermosyphons not only transport heat from sodium to ...

The present work is aimed at evaluating the capabilities of COMSOL Multiphysics® to treat heat transfer in Molten Salt Reactors (MSR). The analyzed situation is represented by the molten salt in turbulent regime flowing through a cylindrical channel surrounded by graphite, with both the fluid and the solid generating power. A suitable validation framework has been set up on the basis of an ...

Mineral precipitation on to the quartz surface of the lamp jackets in UV disinfection process (fouling) has been recognized as a major problem for UV radiation delivery during disinfection operation. Fouling behavior was observed to be induced thermally and influenced by hydraulic character of the UV disinfection configuration. Fouling process involves momentum, heat, and mass transport within ...

A reaction between chemical species is modeled by a particular reaction pathway, in which one reaction is very fast relative to the other one. The diffusion controlled reactions of these species together with a reaction intermediate are described by a system of three transient reaction diffusion equations over a two-dimensional spatial domain. In the asymptotic limit of the reaction parameter ...

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. ...

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 ...

An investigation was undertaken into the suitability of using COMSOL for modeling an aircraft capacitive fuel gauging unit. A model of a sensor immersed in a fluid was developed for rectangular tank geometry with a range of fluid levels and sensor orientation using the electrostatics application mode in COMSOL’s AC/DC module The importance of modeling the capacitance of air was demonstrated. ...

A multiphase porous media model involving heat and mass transfer within a potato chip was implemented in COMSOL 3.5a. The diffusive flux in oil and liquid water was modeled from capillary driven flow while the gas phase was modeled using binary diffusion. A non-equilibrium water evaporation rate was used and Darcy's law for the momentum equation to solve for the convection of each species. ...
