Optimization Module Enables Hybrid Experimental-Numerical Algorithm for 3D Particle Image Velocimetry
In our study of chaotic mixing, 3D velocity measurements (u,v,w) are required for evaluation of a micro mixer using a mix-prediction algorithm. The hybrid approach presented here combines 2D measurements, an imperfect numerical model, and appropriate fitting parameters. Because our ... Read More
Evaluation of Novel Wing Design for UAV
Viable design alternative for the existing and fast growing UAVs which are optimized for unmanned flight is of great demand. Designing of a small scale UAV alternative to the AAI Aerosonde UAV has been considered changing the wing tail configuration of the vehicle analyzing both ... Read More
Design of Precision Magnetic Fields for Fundamental Neutron Symmetries
The traditionally magnetic design process involves guessing at a reasonable conductor geometry, using finite element analysis (FEA) software to calculate the resulting fields, and modifying the configuration iteratively to reach an acceptable solution. Taking the opposite approach, we ... Read More
Magnetorheological Fluid Based Braking System Using L-shaped Disks
This paper presents a novel design of multi-disks Magnetorheological braking system (MR brake) for automotive application. Magnetic saturation in both electromagnetic core and MR fluid is considered in this paper. The electromagnetic analysis of the proposed configuration is carried out ... Read More
Fast Biofluid Transport of High Conductive Liquids Using AC Electrothermal Phenomenon, A Study on Substrate Characteristics
AC electrothermal (ACET) micropumps are based on the temperature gradient caused by Joule heating or an external heat source in the bulk of an electrolyte. In this paper, a 2D simulation was performed to study the effect of substrate thickness and material (glass and silicon) for an ACET ... Read More
Flow Focusing Droplet Generation Using Linear Vibration
Flow focusing microchannels are widely used in droplet generation mechanisms. In this paper, the effect of linear vibration on the flow pattern in a flow focusing structure and the corresponding formed droplets were numerically investigated using COMSOL Multiphysics® software. The ... Read More
Direct Modeling of Packed Bed Channeling
An analysis to quantify the effects of packed bed channeling in the narrow passages of the ISS (International Space Station) CDRA (Carbon Dioxide Removal Assembly) is presented. The CDRA contains two pelletized adsorbent beds to remove CO2 respired by the crew. Each CO2 adsorbent bed is ... Read More
Tuning Sensitivity to Ectopeptidase Rates in the Rat Hippocampus Using Numerical Simulations
We have created and optimized a multiphysics model in COMSOL Multiphysics® software that studies sensitivity to ectopeptidase rates in the rat hippocampus. Ectopeptidases are membrane-bound enzymes whose catalytic domains face the extracellular space (ECS) (Figure 1). They have ... Read More
Tri-Axial Square Helmholtz Coils System to Generate Uniform Magnetic Field Volume
The study of the effects of magnetic field stimulation in biological systems require devices capable of generating homogenous magnetic fields and further guarantee a controlled and repeatable exposure to different samples involved in the experiment [1]. This work presents analysis and ... Read More
Simulation of a Polyimide Based Micromirror
The simulation of a micromirror using polyimide as the structural material is presented. The simulation was used to verify the initial design parameters and to explore the different characteristics of the electromechanical device. For simulation simplicity the electrodes are integrated ... Read More
