As the ancient proverb goes; a beer fridge without beer is like X Factor, utterly pointless. You’d have thought that by clogging up the insides of the fridge with pesky cans of beer you’d cripple it’s thermal performance. As someone once said of Simon Cowell …”O, how wrong you are”. When modelling a can of beer in FloTHERM, in fact when … [Read more...]
Beer Fridge – A Case Study in Thermal Design. Part 3 – Side Up or Upside Down?
The futility of investigating the cooling effectiveness of any empty fridge is beginning to dawn on me, the irony of which is matched only by my new-years-resolution-inspired-sobriety. Never mind, let’s see this particular study through… Whether in a beer ridden fury or in moments of Galilean scientific investigation, you might find yourself kicking the fridge over … [Read more...]
Electromagnetic, Thermal, Stress and Deformation Analysis of a Space-Based Satellite Dish Antenna
This paper presents a multiphysics analysis of a space-based communication satellite antenna. Electromagnetic losses due to induced high-frequency surface currents lead to partial, asymmetric heating of the structure, causing stress and deformation. A final electromagnetic analysis is performed on the resulting deformed structure to determine the effect of the deformation on … [Read more...]
