A Fluid Particle Simulation to Study the Motion Sickness in Semicircular Canal

C. Park[1], J. Lee[1]
[1]Altsoft Inc., Seoul, South Korea

The vestibular systems are very important to balance of body. But some people have vertigo and dizziness caused by vestibular disorder. It is well known how the symptom appears physiologically. The benign paroxysmal positional vertigo (BPPV) which comes from moving an otolith in ... En savoir plus

Validation of a CFD Study of Particle Distribution in Nuclear Workplace

P. Geraldini [1],
[1] Sogin S. p. A., Rome, Italy

Understanding the air flow patterns and aerosol trajectories in ventilated rooms can provide key information for determining where to place early warning and monitoring instruments, and how to minimize hazardous materials in the worker’s breathing zone. The dispersion within rooms can be ... En savoir plus

Thermal Analysis Of A Sealed Battery Power System Enclosure For Underwater Operations

C. H. King Joel [1]
[1] Temasek Polytechnic, Singapore

COMSOL Multiphysics was used to simulate the heat flux from battery cells via conjugate heat transfer physics which consist of laminar flow and heat transfer in solids and fluids. Laminar flow function was used to simulate natural convection of air within the sealed enclosure. Heat ... En savoir plus

Simulating an Adaptive, Liquid-Filled Membrane Lens with COMSOL Multiphysics® Software

V. S. Negi[1], H. Garg[1], B. Singh [2],
[1] Central Scientific Instruments Organisation, Chandigarh, India
[2] Chandigarh College of Engineering and Technology, Chandigarh, India

Adaptive optics control using liquid filled membrane lens is based on the principle of deflection of polymeric membrane. Controlled deflection in membrane leads to controlled focal length. This enhances the focus tuning ability of the system at the same time make optical system compact ... En savoir plus

Multiphysics Simulation for Different Topology of Heat Sink Design
