Resistive heating

  1. Sep 28, 2010 #1
    Hi all, I have made a simulation of resistive heating in Comsol which is basically a gold wire surrounded by air is exposed to 0.1 V and I got the temperature distribution. The numbers seem really high (The temperature is at 2000 K where the ambient temperature is 293) and I would like to make an approximate calculation. I used the heat transfer coefficient formula (heat transfer coefficient equals heat input over surface area times temp. difference) but the temperature difference is 75 K.
    What do I miss here? Thank you in advance.
