Simulation of Silver Evaporation for A Knudsen Effusion Experiment Under Zero Gravity

D. Henriques[1], H. Fritze[2], M. Schulz[2], T. Markus[1]
[1]Hochschule Mannheim, Germany
[2]TU Clausthal, Germany

Material constants are required to develop new materials for the aerospace, automotive and energy industries. With these highly accurate experimentally determined data, complex metallurgical melting processes can be simulated later, for example. The microstructure of the new alloy can be ... En savoir plus

Simulating Obscurants Under High Energy Laser Illumination

S. Du[1], A. Strikwerda[2], J. Miragliotta[2]
[1]Winston Churchill High School, USA
[2]Johns Hopkins University Applied Physics Lab, USA

Here we present a simulation for evaluation of novel obscurant candidates under high-energy laser (HEL) illumination. This approach incorporates thermal modeling into obscurant characterization, allowing for evaluation of the temperature increase of the candidate obscurants as well as ... En savoir plus

Assessing Reliability of Embedded Resistor Designs in Integrated Circuit

R. Wulandana[1], P. Wang[1], L. McCary[1], S. Alzeq[1]
[1]State University of New York (SUNY) at New Paltz, USA

Localized Joule heating within integrated circuit (IC) chips is the leading cause of non-uniform temperature distribution within the circuit structure of the chips. Such variation in temperature enhances the biased diffusion of metal atoms along current carrying interconnects, a ... En savoir plus

High Current and Multiphysics Modeling of Carbon Fiber Reinforced Polymers (CFRP) Plates and Joints Under Lightning Strike Conditions

S. Biswas[1], M. Mirotznik[1]
[1]University of Delaware, USA

This paper presents multiphysics modeling of coupled thermal-electrical behavior across the composite joints formed by highly anisotropic conductivity materials such as carbon fiber reinforced polymers (CFRP) under lightning strike conditions and demonstrates the driving physics behind ...

[2]Dipartimento di Ingegneria Aerospaziale e Meccanica, Seconda Università degli Studi di Napoli, Aversa (CE), Italy

A two dimensional instationary analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure on a glass substrate by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. COMSOL Multiphysics ... En savoir plus

Using COMSOL® for the Development of the UK’s Second Hyperloop Prototype

A. Jocas [1], I. C. H, Chan [1], A. Malekos [1], H. P. Chan [1],
[1] The University of Edinburgh, UK

Hyperloop is a future concept of mass transportation proposed by Elon Musk. It uses electromagnetic propulsion to accelerate a passenger or cargo pod through a low-pressure tube. HYPED, the University of Edinburgh’s Hyperloop Team has created a prototype that uses linear halbach arrays ... En savoir plus

Magneto-Mechanical-Thermal Couplings for the Pulsed Magnetic Technology with Single-Turn Coils

O. Maloberti [1], P. Sansen [1], D. Jouaffre [2], D. Haye [2],
[1] ESIEE Amiens, France
[2] PFT Innovaltech, France

Single turn coils produce AC and transient magnetic fields in pulsed magnetic technologies for which magneto-harmonic and transient magnetic analysis can be primarily performed. We suggest studying one single turn coil example made of a conducting massive coil, an optional conducting ... En savoir plus
