We present numerical results involving microorganisms adhering to a plane surface submitted to a shear flow. The purpose is to have a better understanding of the removal mechanisms occurring during the cleaning in place of food processing equipments. The biological cell, i.e. the microorganism, is modelled as a rigid obstacle embedded in the bottom wall of the fluid domain. Shear induced ...

Traditionally the design cycle for magnetic fields involves guessing at a reasonable conductor and magnetic material configuration, using finite element analysis (FEA) software to calculate the resulting field, modifying the configuration, and iterating to produce the desired results. We take the opposite approach of specifying the required magnetic field, imposing it as a boundary condition on ...
Designers of electro-optic modulators and related devices often use separate tools to study the optical and electrical portions of the device. The flexibility of COMSOL Multiphysics makes it possible to construct unified models of EO phenomena including realistic waveguide profiles and anisotropic material properties. We demonstrate the use of the RF Module to compute both RF and optical ...

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 highly variable results and would be labour, resource and time intensive. Thus modeling of the microwave ...

The mechanical simulation and analysis of the cantilever-to-anchor configuration for an out-of-plane structure used in transducer applications is reported. The polymer-based Buckled Cantilever Plate “BCP” structure, gives the ability to orient an active device from a horizontal to a vertical position, once assembled. In this paper we compare four different cantilever-to-anchor configurations: ...

Whilst initially developed as a diagnostic aid to improve echogenicity in ultrasound imaging, gas-filled lipid microbubbles are now emerging as a next generation \'theranostic\' tool in the medical arena. Here, their therapeutic potential has now been realized through their unique capability to deliver molecular species such as drugs and genes by means of disrupting the cell membrane in response ...

This abstract addresses the effect of scaling in air gap MOSFETs and determination of functional relationship between scaling parameter and sensitivity, frequency response. The modelling of the MOSFET and its simulations has been carried out using COMSOL Multiphysics. An air Gap MOSFET in its simplest form can be imagined to be one obtained by replacing the dielectric in a MOSFET with air. The ...
Reliability Enhancement of Bio MEMS based Cantilever Array Sensors for Antigen Detection System using Heterogeneous Modular Redundancy

The objective of the work is to propose a reliability enhancement model for antigen detection system (ADS) using bio MEMS based cantilever array sensors using heterogeneous modular redundancy technique. The reliability of the ADS is expressed in terms of the constituent sub systems which are heterogeneous not only in their respective structures and behaviors but also in their forms. The possible ...
