Numerical Simulation of Bull's Eye Grating Using COMSOL Multiphysics® Software

D. Ray [1], A. Prabhakar [1],
[1] Indian Institute of Technology Madras, Chennai, Tamil Nadu, India

Plasmonic gratings like bull's eye can localize E field due to excitation of surface plasmons and when integrated with Ge-on-Si photodetector they can help in fabrication of ultra small photodiodes with high sensitivity. We have numerically carried out a frequency analysis for the ... Read More

Mathematical Modelling of Evaporation of Water Using Steam–Unitary Model Analysis

D. Rakshit [1], S. Ramanathan [2],
[1] Indian Institute of Technology Delhi, India
[2]Centre for Science and Environment, New Delhi, India

Multiple effect evaporators use steam of temperature 120-200°C as a source of heat to evaporate water from solutions. Multiple effect evaporators are widely used by the food, desalination and wastewater treatment industry. In the present study as a proof of concept, multi-physics ... Read More

[1] Indian Institute of Technology Madras, Chennai, Tamil Nadu, India
[2] Defense Research and development Organization, Bangalore, Karnataka, India

Laminar forced convection is studied in a vertical rectangular channel with seven discrete heat sources and dummy heat sources mounted on a wall. The position of seven heat sources is fixed in an optimal arrangement. The heat transfer effects are investigated by numerical simulation and ... Read More

Transient Diffusion Modeling of Methane Plume and Source Localization

S. K. Nayaka[1],, S. Roya [1],, K. Ghosha [1],, S. Aroshb [2],, S. Prakashb[2],, S. P. Duttaguptaa [1][2]
[1] Center for Research in Nanotechnology and Science, IIT Bombay, Mumbai, Maharashtra, India.
[2] Dept. of Electrical Engineering, IIT Bombay, Mumbai, Maharashtra, India.

Methane detection and quantification is of great importance due to its natural abundance, potential to cause explosions and known greenhouse effect. Leak detection and concentration monitoring at source is highly challenging as CH4 is odorless and colorless. This can be performed ... Read More

Establishing Tolerances and Limits of Failure for Sample and Reagent Flow Using COMSOL Multiphysics® Software

S. Kumar [1], D. Dendukuri [1]
[1]Achira Labs, Bangalore, Karnataka.

Microfluidics is the science of manipulating and controlling fluids at the micron scale. Although, fluid flow in standard geometries can be determined easily by analytical methods, a more rigorous computational model is required for custom geometries. Achira’s microfluidics cartridge has ... Read More

Modal Analysis of Elastic Ring Squeeze Film Damper for Small Gas Turbine Engines

S. Thennavarajan[1][2], P. Jeyaraj [1], L. P. Manikandan [2], S. S. Kulkarni [2], S. Jana [2],
[1]Department of Mechanical Engineering, NITK, Surathkal, Mangalore, Karnataka, India
