COMSOL Multiphysics® software was used to model radial source flow in two dimensional homogeneous porous media. Two-Phase Darcy's Law (tpdl) is used to model miscible viscous fingering. Fingering patterns obtained on using different mesh are discussed. Evolution from 'flowers' to ... 詳細を見る

This poster studies catalytic micropumps and their ability to induce fluid flow on the microscale. The goal of the study is to design a long-distance, directed convective loop. An array of catalytic micropumps was constructed in the domain, comprised of two distinct catalysts in an ... 詳細を見る

We present a novel method for concentrating and focusing small analytes by taking advantage of the nonuniform ion distributions produced by thick electric double layers (EDLs) in nanochannels with heterogeneous surface charge. Specifically, we apply a voltage bias to a gate electrode ... 詳細を見る

A recently published conservative algorithm for simulating reactions and transport in moving domains have been extended to models in which cell kinematics are coupled with intracellular dynamics. For this, the method that combines a Eulerian approach with tracking an explicit boundary ... 詳細を見る

Ionic polymer-metal composite (IPMC) materials are promising candidates for soft robotics and artificial muscle applications. The primary actuation mechanism in such devices is ion migration in a polymer membrane, localized swelling, and a corresponding overall material deformation, ... 詳細を見る

Vortex ring can be useful to generate thrust force for e.g., jellyfish, but its mechanism has not been clarified. In this field, it seems that numerical simulation has an important role of understanding the propulsion mechanism of creature. A vortex ring in a tube, refered to confined ... 詳細を見る

There is great interest in developing all-solid-state lithium-ion batteries. They are ideal micro-power sources for many applications in portable electronic devices, electric vehicles and biomedical engineering. It is known that all-solid-state lithium-ion batteries are often fabricated ... 詳細を見る

The purpose of this study was to investigate the impact on number of baffles placed in horizontal- or vertical-alignment of an anaerobic baffled reactor (HABR and ABR, respectively). Computational fluid dynamics was used to evaluate hydraulic performance of each and determine what number ... 詳細を見る

Air supply hoses are also predominantly used in the medical industry to aid in patient oxygen intake. In many situations, the outside of the hose can be contaminated with chemicals, especially if the hose lies on the ground in an environment where chemicals are easily found. Permeation ... 詳細を見る

The finite element method was used for simulating the dielectric response of polymer matrix dielectric composites with randomly and evenly distributed fillers. The dielectric simulation of the composite materials was conducted using a time harmonic-electric current solver in the AC/DC ... 詳細を見る
