Modeling of Supercapacitor

G. Madabattula[1], S. K. Gupta[1]
[1]Department of Chemical Engineering, Indian Institute of Science, Bangalore, Karnataka, India

Low cost high energy density batteries that can be charged and discharged rapidly are required in a number of applications. Tapping energy from renewal resources such as solar, wind and tide requires rapidly generated energy to be first stored and then used round the clock. Storing ... Read More

Flow of Dry Foam in a Pipe

M. Divakaran[1], S. K. Gupta[1]
[1]Department of Chemical Engineering, Indian Institute of Science, Bangalore, Karnataka, India

Due to the coupling of foam flow with foam generation step, the earlier studies on foam flow have not led to consistent results. An increase in flow rate to obtain ?P vs. Q data changes the foam under investigation itself. The controlled experiments carried out earlier in our group ... Read More

Optimal Utilization of Railgun

N. R. Mahajan[1], S. B. Patel[1], Z. A. Khan[1]
[1]Department of Electrical Engineering, Indian Institute of Technology Hyderabad, Hyderabad, Andhra Pradesh, India

Railgun is an electrically-powered gun that accelerates a conductive projectile along magnetic metal rails. Various factors increase the projectile velocity. Each method has its own advantages and disadvantages. While increasing the projectile velocity, one has to keep in mind the ... Read More

Development towards Non-invasive Breast Cancer Imaging using Novel Estrogen Conjugates Fluorescent Dye

Francis .K. J.[1], I. Jose[1]
[1]Christ University,Bangalore, Karnataka,India

Determination of Estrogen Receptor [ER] status is a key in detecting cancer pathogenesis at early stage. In our work we discuss Near Infrared Fluorescence [NIRf] Molecule Optical Imaging Diagnostic modality for early detection of breast cancer. A novel target-specific NIRf dye conjugate ... Read More

Finite Element Analysis of a Fiber Bragg Grating Accelerometer for Performance Optimization

N. Basumallick[1], A. Ghosh[1], P. Biswas[1], K. Dasgupta[1], S. Bandyopadhyay[1]
[1]Fiber Optics Laboratory, Central Glass and Ceramic Research Institute, Kolkata, West Bengal, India

Sensitivity of a cantilever-mass based fiber Bragg grating (FBG) accelerometer can efficiently be tailored by altering the distance between the axis of the FBG sensor to the neutral axis of the cantilever. To accomplish that in general, a backing patch is used to mount the FBG on the ... Read More

Diffusion Modeling in TGA in Context of CO2 Gasification of Char

G. Samdani[1], S. Mahajani[1], A. Ganesh[1], P. Aghalayam[2], R. K. Sapru[3], D. K. Mathur[3]
[1]Department of Chemical Engineering, Indian Institute of Technology Bombay, Mumbai, India
[2]Indian Institute of Technology Madras, Chennai, India
[3]UCG Group, IRS, ONGC, Chankheda, Ahmadabad

The Thermo- Gravimetric Apparatus (TGA) is often used for kinetics determination. In TGA setup, gasification reaction may be limited by the reach (diffusion) of the gasification agent to the internal surfaces of the char particles. In addition to this, after some time, ash is formed ... Read More

Miscible Viscous Fingering: Application in Chromatographic Columns and Aquifers

S. Pramanik[1], G. L. Kulukuru[1], M. Mishra[1]
[1]Indian Institute of Technology Ropar, Rupnagar, Punjab, India

When a less viscous fluid displaces a more viscous one in a porous medium or Hele-Shaw cell, the interface between the two miscible fluids does not remain flat and deforms into fingers growing in time [1]. It occurs due to the faster movement of less viscous fluid than the more viscous ... Read More

Numerical Study of Navier-Stokes Equations in Supersonic Flow over a Double Wedge Airfoil using Adaptive Grids

V. Gopal[1], R. Kolluru[1]
[1]BMS College of Engineering, Bangalore, Karnataka, India.

Numerical study of aerodynamic characteristics in steady laminar supersonic flow over a double wedge airfoil is carried out using commercially available finite element based CFD tool COMSOL Multiphysics. The aerodynamic characteristics of double wedge airfoil like lift and drag are ... Read More

Effect of Geometry of the Grooves on the Mixing of Fluids in Micro Mixer Channel

V. Ranjan[1], A. Kumar[1], G. Prakash[1], R. Mandal[1]
[1]Department of Mechanical Engineering, Indian School of Mines, Dhanbad, Jharkhand, India

Understanding the flow fields at the micro-scale is a key to develop methods of successfully mixing fluids for micro-scale applications. This paper investigates flow characteristics and mixing of three different geometries in micro-channel. A Circular groove micro mixer has been designed ... Read More

The Spiral RF MEMS Switch in COMSOL Multiphysics

K. M. V. Swamy[1], B. G. Sheeparamatti[1], G. R. Prakash[1]
[1]Basaveshwara Engineering Collage, Bagalkot, Karnataka, India

This work presents the study of spiral RF MEMS switch which has low actuation voltage due to spiral structure. This work is inspired by the superior performance of electrostatic RF MEMS switches over the conventional state-of-the-art solid-state devices and the potential applications in ... Read More
