: 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 ...

Seals or gaskets that are compressed between walls of a container are important to many industrial applications. Understanding the performance of such seals requires an understanding of the microscopic geometry of the sealing surfaces, because the fluid seeps around the undulations of such surfaces. This paper presents strong computational evidence that the microgeometry of such surfaces depends ...
Implicit LES for Two-Dimensional Circular Cylinder Flow by Using COMSOL Multiphysics® Software - new
Keisoku Engineering System Co.,Ltd., Tokyo, Japan
In this paper, implicit Large Eddy Simulation (LES) based on finite-element analysis is performed in order to investigate two-dimensional circular cylinder incompressible flow. Implicit LES attempts time-dependent flow computation with no explicit turbulence model. Here, two types of circular cylinder with/without surface roughness, are treated. The Reynolds number Re based of the diameter of ...

The flow morphology of two immiscible fluids in a microfluidic device finds numerous applications such as emulsification, synthesis of nanomaterials , lab-on-a-chip devices and biological analysis . It offers many advantages over the conventional macroscopic devices because of its availability for higher surface to volume ratio, ability to handle small volume of fluids, easier process ...

Nowadays, gas and nuclear waste storage, shale gas and EOR exploitation rise the need to understand and predict the fate of multiphase flows in the underground. Various formulations for multiphase flow arise from different linear combinations of governing equations and choice of associated unknowns. Each formulation has its own benefits and drawbacks; and the optimal may vary depending on the ...

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 ...

This paper deals with the simulation of mathematical model for supercritical extraction. Reverchon, 1996 extracted sage oil using supercritical extraction method from sage leaves at 9 MPa and 50 ᵒC. Four mean size of sage leaves ranging from 0.25 to 3.10 mm were taken for extraction with other experimental conditions and process parameters. Experimental results were fitted in the model developed ...

PCR (Polymerase Chain Reaction) is a recent well researched technique which can be employed to obtain an amplified DNA (Deoxyribonucleic Acid). A continuous flow polymerase chain reaction with integrated MEMS based design micro heater for DNA amplification is implemented. Temperature zone is obtained by natural heat conduction rather than making use of typical silicon thermal cycler. Inter ...
