Wanted: CFD Example of Free Convection around a light bulb
 

Can anyone point me to an example (image or video) of the free convection around a light bulb? I need to find an example showing the velocity field generated by the thermal plume from a light bulb (any wattage at this point is fine.)
If a light bulb is not available, then I can settle for a simple sphere or even a 2D cylinder, but I need to have the scale of the velocity vectors or contours included.

As simple as this may seem, I can't find a suitable example on the web.

Thanks.

You can look for CFD Modeling of laser plume. Only problem is the wattage is too high. Check online or if possible in nanoscience journals.
