: One of the most commonly used techniques for quantification of beating forces exerted by cardiomyocytes is culturing them on a bed of vertical microcantilevers or microposts. The position of the microcantilevers is observed through advanced imaging techniques and the displacements are observed over a period of time. The stiffness of the microcantilevers is known and thus the force can be ...

A model for the conjugate simulation of heat and moisture transfer inside porous materials and fluid domains is implemented in COMSOL Multiphysics®. The results of this model are compared with those obtained through a simplified approach: the line-source approach. The models are both validated with experimental data and with numerical results from other authors. On the one hand the conjugate ...

Electric power, in cities or for power plant outflow, is most often transmitted through underground cables. Due to increased electricity demands power suppliers make large investments to house these cables in deep or shallow tunnels. The thermal environment is complex, with different kind of cables placed in different configurations, transmitting different powers. These are hard to take into ...

Design and manufacture of thrusters for producing very low thrust force in the range of milli or micro newtons using micronozzles has been actively developed in the last decade. The nature of propellant flow in such micronozzles differs from that of macro nozzles. In micronozzles, viscous effect dominates; hence the flow is always in laminar regime with high viscous losses. Objective of this ...

The aim of this study is to design a new concept of shrouded probe that meets the ISO 2889 requirements and it is suitable for small-ducts installation. In order to reduce the construction costs they have been considered standard stainless steel welding fittings manufactured according to ASME/ANSI specifications. In particular, with the numerical simulations, they have been firstly evaluated ...

We present computer simulation results for PEM fuel cells using COMSOL Multiphysics® software. We have developed novel PDE equations at NPL from first principles and these are more realistic than models typically used in literature. The theory includes Maxwell-Stephan and Nernst-Planck equations for the diffusion and electrochemistry as well as equations governing electrostatic and stress/strain ...

Viscous fingering is a topic of interest since the beginning of computational fluid dynamics. Here we focus on the classical constellation of miscible displacement, as it has been investigated in Hele-Shaw cells. A temperature or salinity front is entering with a fluid that has a different viscosity. The pure 1D flow is destabilized by the Saffman-Taylor instability. Using COMSOL Multiphysics® ...

This contribution is devoted to the mathematical modeling of the AC electroosmotic micropumps in COMSOL Multiphysics and Matlab. The mathematical model involves the microchannel surroundings and several AC-voltage driving modes. The weak form has been used for handling singularities and other problems. The system dynamic behavior and conditions at the phase interfaces will be discussed.

In the production of high quality materials by a heat treatment, it is indispensable to accurately predict the temperature inside the furnaces being employed. In this work we develop a turbulent combustion model for the heat being released by gas burners inside a shaft kiln. Turbulent combustion is the strongly coupled phenomena of the chemically reacting fuel and oxygen in a turbulent flow. ...

Electro refining is one of the important step in the Pyro processing nuclear spent fuel with molten salt. The electro refiner is a process vessel consists of anode ,cathodes and stirrers and ultra –high pure argon gas is provided at the top for inert atmosphere and at the bottom a cadmium layer is provided. The vapor pressure of the cadmium is high at the operating temperature, the cadmium vapor ...
