To help show the effects of natural convection on fluid flow (buoyancy-driven flow), I've modeled a simple coffee mug with a spinner positioned directly above. The spinner is free to rotate about its axis and will begin to turn as vertical air velocity increases. I've assumed a heat generation of 300 Watts inside the fluid in the mug (water).
No need to get into the complexities of how microwaves work to heat things, I just want to see the effect of the hot mug on air flow, but if you must know: About Microwave Ovens
