Hi all,

I'm doing some heat transfer numerical simulation of a thinfilm heater that
has a lot of 90-deg turns. The heater is made of evaporated gold on a
single crystal LSN substrate. The dimension is 400um wide and about 1um
thick, and I'm applying a 5-15VDC current-unlimited power to the heater. I
understand that the method of fabrication might have introduced some
thickness non-uniformity at the corners. But if I assume the thickness is
uniform, is electrical conduction at corners differ noticeably than for a
straight path (like in fluid flow)? Or does the electron spatial and
temporal scale of travel make the existent of the corner irrelevant?

Any suggestions and/or references would be greatly appreciated.
