Modeling Confinement in Quantum Dot Solar Cells

J. Liu [1], M. Zubaer Hossain [1],
[1] Department of Mechanical Engineering, University of Delaware, Newark, DE, USA

The efficiency of the first and second generations of solar cell has hardly seen dramatically increase over the years, in which most PV cells cannot use about 55% of the energy of sunlight because a single material can not capture the entire spectrum of sunlight. To achieve the objective ... Read More

Study of Bending Losses in Optical Fibers using COMSOL Multiphysics®

Ashitosh Velamuri [1], Krupal Patel [2], Ishan Sharma [2], Shakti Gupta [2], Pradeep Kumar Krishnamurthy [1],
[1] Center for Lasers and Photonics, Indian Institute of Technology Kanpur, Kanpur, Uttar Pradesh, India
[2] Department of Mechanical Engineering, Indian Institute of Technology Kanpur, Kanpur, Uttar Pradesh, India

In FTTH, optical fibers are frequently bent at the corners of the walls causing the propagating light in the fiber to radiate away which results in transmission losses and limits reach of the fiber network. A large number of studies have been reported in the literature to compute bend ... Read More

Adaptive Mesh Refinement: Quantitative Computation of a Rising Bubble Using COMSOL Multiphysics®

T. Preney [1], P. Namy [1], J. Wheeler [1]
[1] SIMTEC, Grenoble, France

The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... Read More

Light-tissue Interaction Modeling Using COMSOL Multiphysics® for Multi-layered Soft Tissues

Vysakh V [1], Sujatha Narayanan Unni [1],
[1] Indian Institutes of Technology Madras, Chennai, Tamil Nadu, India

Soft tissues are longest tissue structures found throughout a human body. It plays a vital role in connecting, providing support or surround other structures and organs of the body. Muscles, skin, tendons, ligaments, nerves, fibrous tissues, fat, blood vessels are commonly classified as ... Read More

Design and Simulation of a MEMS-Based Ultrasonic Transducer for Viscosity Sensing Applications

Rahul Goyal [1], Divya Mohan Yadav [1],
[1] Indian Institute of Science, Bangalore, Karnataka, India

Technologies based on micro electro mechanical systems (MEMS) present advantages for rheological applications as they enable the fabrication of smaller sensors with faster response times. In this work we propose fabrication parameters and simulation of a MEMS viscometer. This research ... Read More

Two-Phase Flow Modeling of Metal Vaporisation under Static Laser Shot Using a Double ALE Method
