Linear Induction Motor (LIM) has been identified as a key element for electromagnetic launching technology. The stator part of the motor when energized induces a linearly moving magnetic field which consequently produces a thrust force on the rotor part of the motor. Thus it accelerates ... Read More

This paper presents a finite element (FE) model of the scattering studies of cylindrical pressure housings made of different metallic alloys such as aluminium, stainless steel 316L and titanium. Understanding the acoustic scattering behavior of underwater objects helps in improving ... Read More

Wavelength Bit-rate Tunable Silicon – Organic hybrid Modulator using commercially Available HLD

Arathy krishna 1, Dr Prita Nair1
1Shiv Nadar University Chennai

On-chip photonic modulators designs currently use NLO material stacks such as LiNbO3 or BaTiO3 on Si or use current injection across silicon waveguides to induce phase change required for optical modulation(Li 2020)(Li 2019). The other silicon compatible option explored is silicon ... Read More

Single membrane MEMS-based acoustic emission sensor for multi-frequency detection

Durgesh Tamhane1, Saurabh Arun Chandorkar1
1Indian Institute of Science

Acoustic emissions generated by active defects in structures, like bridges, aircraft, and pipelines, play a crucial role in detecting flaws in their structural integrity by non-destructive evaluation techniques. Commercially used acoustic emission (AE) sensors are made of piezoelectric ... Read More

Topologically enhanced guided mode resonance sensing of fluid refractive index variations

Swathy R1, Likhith R1, S M Harshitha1, Kaustav Bhowmick1
1PES University, Bangalore, Karnataka, India

The present work explores the integration of guided mode resonance (GMR) structures and topological photonics, characterized by the presence of Jackiw-Rebbi (J-R) solution. The developed surface enhanced GMR structure may serve as a platform for refractive index sensing across various ... Read More

Simulating electro-vortex flow in a liquid metal battery electrode: comparing COMSOL with OpenFOAM

Swapnil Soni1, Ravi Kant1, Avishek Ranjan1, Atul Srivastava1
1Department of Mechanical Engineering, IIT Bombay, Mumbai, Maharashtra, India

In conducting fluids, electro-vortex flows (EVF) can arise due to the interaction of a diverging/converging current with its own magnetic field [1]. When the current diverges, the Lorentz force is non-conservative, leading to EVF in an initially quiescent fluid. EVF is observed in many ... Read More

Three Dimensional Numerical Analysis of an Eddy Current Flow Meter

1Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu

Liquid Metal Fast Breeder Reactor (LMFBR) employs molten sodium as coolant due to its suitable neutronic and thermal properties. Measurement of coolant flow rate is a very important factor both from operational and safety aspects of a fast reactor. Good electrical conductivity of liquid ... Read More

COMSOL LiveLink for MATLAB code for topology optimization of conjugate heat transfer problems


Topology optimization of conjugate heat transfer problems is an relatively intricate problem due to the coupled nature of Navier-Stokes equation, continuity equation and energy equation. In any density based topology optimization code, the major parts are finite element analysis, ... Read More
