Bye to all,
are days now that I try to make a simple transitional thermal analysis on an aluminum block heated by an electrical resistance. I can't understand why after 30 seconds I find negative temperatures even if the starting temperature is 293 k. I'm desperate! Help me!
Good morning to all
I have to see how temperatures are distributed in a heatsink for a lighting circuit. . .
the particular is so composed. .
heatsink that is also structure of the lamp.. .
niche for circuit (+lights led) inside the heatsink. . .
glass with seal as upper casing. . .
all in...
