Design of a MEMS Capacitive Comb-drive Accelerometer
In this work, a MEMS low-g accelerometer with three sensitive directions is designed for health monitoring applications. The accelerometer may have different sensitivity in different axes. The proof-mass of the device is suspended by four serpentine springs, and the comb drive structure ... Read More
Electrophoresis and Electroosmosis in the Intracellular Transport of Macromolecules
Electric fields are present in biological systems at multiple spatial and temporal scales. Electroosmotic flow results from the action of electric field on the electrical double layer, formed at the fluid/solid or fluid/membrane interface and characterized by its zeta-potential. For the ... Read More
Model of a Heavy Metal Adsorption System using the S-Layer of Bacillus Sphaericus
A bidimensional and pseudo homogenous model was proposed for the study of mass transfer in the bioadsorption process of chromium VI in the S-layer of immobilized Bacillus sphaericus in a packed column. The implementation of such a model in COMSOL Multiphysics will be explained in detail ... Read More
Modeling of Microwave Heating of a Rotating Object in a Domestic Oven in COMSOL Multiphysics
Domestic microwave ovens are notorious for their uneven heating of food materials. This is caused by a varying electromagnetic field whose variation is caused by a number of factors dependent on the oven and the food parameters. Experimental validation of heating would therefore give ... Read More
Simulation of Dendritic Solidification in Cubic and HCP Crystals by Cellular Automaton and Phase-Field Models
A cellular automaton (CA)-finite element (FE) model and a phase field (PF)-FE model were used to simulate equiaxed dendritic growth during solidification of cubic and hexagonal crystals. The governing equations of PF model include three coupled partial differential equations (PDE) for ... Read More
Conjugate Heat Transfer for Wireless Power Amplifier
Wireless power transfer is an emerging technology with many potential applications. This technology may be of particular value when remotely controlled in extreme physical conditions. This study explores the ability of the COMSOL software to predict the performance of thermal management ... Read More
Analyzing Drug Delivery and Osteoblast Growth on a Porous Scaffold in a Perfusion Bioreactor
Implantable Collagen sponges are used in Spinal Surgery as Drug Delivery Scaffolds. An optimal concentration of growth factor that strikes a balance between bone growth and adverse diffusion effects is difficult to find. The porous sponge also serves as a scaffold for Osteoblast growth, ... Read More
MEMS-Based Microdroplet Generation with Integrated Sensing
This paper presents model development and simulation results for a microdroplet generator capable of internally measuring the volume of dispensed droplets. The system’s integrated sensing is enabled by storing compressible gas adjacent to the dispenser’s liquid reservoir. During ... Read More
Boundary Element Technique in Petroleum Reservoir Simulation
Petroleum reservoir simulation is a process of modeling the complex physical phenomena inside a reservoir. This study presents an application of an analytical based numerical scheme so called the Boundary Element Method (DRBEM). It is proven to be able to provide a computationally ... Read More
Thermal Stress in a Zero Thermal Expansion Composite
A series of 2-D finite element models of a ZrO2-ZrW2O8 composite system were created in COMSOL Multiphysics to study the effect of pores between the matrix (ZrO2) and filler (ZrW2O8) materials. Pores were modeled as ellipses concentric with the filler particles. Seventeen model ... Read More
