[1]CSIR - National Chemical Laboratory, Pune, Maharashtra, India
[2]Reliance Industries Ltd., Reliance Technology Group, Navi Mumbai, Maharashtra, India
[3]CSIR - Central Electrochemical Research Institute, Karaikudi, Tamil Nadu, India

A Proton Exchange Membrane Fuel Cell (PEMFC) comprises a membrane-electrode assembly sandwiched between two conducting ‘monopolar’ plates having engraved gas flow channels, also called the flow field. The purpose of the flow field is to provide sufficient residence time for the gases to ... Read More

Temperature and Acceleration Sensitivities of a Dual Cavity Fabry-Perot Interferometer new

[1]R. K. Banyal
Indian Institute of Astrophysics, Bengaluru, Karnataka, India[1]

The numerical study of temperature and acceleration sensitivities of a dual cavity Fabry-Perot (FP) interferometer is carried out using finite element method. The optical cavities are formed by machining two side-by-side circular bore of 12 mm each on a monolithic block of low expansion ... Read More

An Approach to Modeling Vacuum Desorption new

C. F. Gomez[1], R. Schunk[1], R. F. Coker[1], J. Knox[1]
[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The objective of this simulation effort is to develop a mathematical model of vacuum desorption on a POC (Proof of Concept) canister loaded with Zeolite 13X/5A . This canister contains a pelletized adsorption bed which is used to adsorb H2O and CO2. Once this bed is fully saturated with ... Read More

Analysis of Flow in a Microfluidic Device: Pressure Drop, RTD and Mixing

A. Kulkarni[1]
[1]NCL, Pune, Maharashtra, India

Continuous flow reactors are recently being used for lab scale synthesis as well as pilot scale manufacturing of high value low volume chemicals. Here we present our work on a new configuration of flow reactor that includes several 1800 bends and yet a varying radius of curvature thereby ... Read More

Solution of Poroelastic Equations with Different Base Variables Using Equation-based Modeling

M. H. Akanda [1], Y. Cao [1], A. J. Meir [1],
[1] Department of Mathematics & Statistics, Auburn University, Auburn, AL, USA

Poroelasticity equations describe the interaction between fluid flow and solids deformation within a porous medium. Modeling of poroelasticity is coupling between elastic deformation of porous materials and Darcy’s law. Poroelasticity has numerous real world applications such as in ... Read More

Model of Natural Convection above Horizontal and Inclined Plates

I. Khan [1], V. Tsitsopoulos [2], J. Dold [3],
[1] University of Central Lancashire, Preston, United Kingdom
[2] AMEC, London, United Kingdom
[3] University of Manchester, Manchester, United Kingdom

The boundary layer flow above an isothermal flat plate inclined at a small angle to the horizontal is analyzed. Inclination effects are initially investigated as a perturbation to the horizontal flow by obtaining a fourth order series solutions valid near the leading edge of the plate ... Read More

A Numerical Heat Transfer Analysis on an Implantable Phase-Change Actuated Peristaltic Micropump

F. Forouzandeh [1], D. A. Borkholder [1],
[1] Rochester Institute of Technology, Rochester, NY, USA

Advances in protective and restorative biotherapies have created new opportunities to address vestibular disorders, deafness, and noise induced-, sensorineural-, and age-related hearing loss. Controllable and implantable drug delivery micropumps are essential for therapy development in ... Read More

Boundary Arbitrary Lagrangian-Eulerian and Deformable Boundary Perturbation Method

J. Rivero-Rodriguez [1], B. Scheid [1],
[1] Université Libre de Bruxelles, Brussels, Belgium

Partial differential equations on unknown domains is a mathematical problem that arises in many applications. Several examples can be easily found in the dynamics of free surfaces in fluid dynamics or in fluid-structure interactions. In many situations, large deformations are encountered ... Read More
