Demystifying Electromagnetics, Part 5 – Ferromagnetic Cores

A coil of wire creates a magnetic field when a current passes through it. The…

Demystifying Electromagnetics, Part 4 – Inductors

Welcome to Part 4 in this blog series that hopes to demystify electromagnetics for those of you who might have a background in mechanical engineering, fluid flow and heat transfer. Ultimately we’ll be getting onto electric motors, generators, induction cooking, levitation, loud speakers etc. etc. but for now some more basics – Inductors….

Happy Geek Pride Day, but what does the ‘B’ stand for?

Can Simcenter Flotherm model Simcenter Flotherm modelling Simcenter Flotherm modelling the Mandelbrot set? Yes, but only on Geek Day….

Demystifying Electromagnetics, Part 3 – Magnets

Why do magnets attract or repel and what’s that got to do with conducting loops of wire? Peter and Petronella Proton help explain….

Electric Fields without and with a conductor

Demystifying Electromagnetics, Part 2 – Wires

Ohm’s Law is just a flow rate, analogous to fluid mass flow. What’s that got to do with EM and what is Temperature and Joule heating anyway?…

Demystifying Electromagnetics, Part 1 – Fields and Analogies

This blog series will strive to demystify (low frequency) EM by way of pictures and analogies, with as few equations as possible, by introducing a series of applications of increasing complexity. In this first blog we’ll and start to look into the electric field with the use of some analogies….

Trace, plane and thermal via heat spreading

Thermal Influence on Maximum Current Carrying Capacity

Superconductors aside, anything that conducts electricity will dissipate heat. The more current that flows, the more heat is dissipated, the hotter things will get. At some point a thermal limit is reached that imposes a maximum current carrying capacity constraint….

VortexDome

Flow Visualization and the Beauty of the Vortex Dome

Fluids tend to be transparent, which is problematic for flow visualization. Rheoscopic fluids get round this by seeding the flow with reflective particles….

Chaotic Fluid Dynamics Part 4 – Finding Feigenbaum

A 29 year old ambition finally achieved with the help of Simcenter FLOEFD for NX!…
