Simulating the Pressure in an Ultrahigh Vacuum System
The ETpathfinder research facility in the Netherlands was built in anticipation of the proposed Einstein Telescope (ET), a third-generation observatory of gravitational waves.
Analyzing LED Bulb Designs with Heat Transfer Simulation
LED bulbs are billed as more energy efficient than traditional bulbs, but they are not 100% efficient in turning electricity into light, making thermal management a vital design consideration.
Fully Coupled Hydromechanical Modeling of Fractured Media
Dr. Qinghua Lei of ETH Zürich demonstrates a novel method for modeling fully coupled hydromechanical processes in fractured media with 2 examples: fluid injection and underground excavation.
