<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>I speak from VERY limited experience, however the simple version appears to be to “pull” the air over the surface rather than push it. They used a large fan to evacuate the room and provided small controlled inlets for air to enter and flow over the surface. The smoke is simply from colored smoke sticks, though I’m not sure of the source of those. <BR>

I’m curious though how representative that is of the actual “Flow” over the object. <BR>

I was thinking one might determine what the cooling airflow looked like around and through our electric motors.<BR>
