Analyzing LED Bulb Designs with Heat Transfer Simulation

July 22, 2021

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

July 1, 2021

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.

Fine-Tuning an HVAC System Design with Simulation

June 23, 2021

Do you find your office too hot, too cold, or just right? Using simulation, HVAC system engineers can assess indoor climate conditions and ensure maximum comfort among a building’s occupants.
