higher temperature in the simulation

kcgmech · March 10, 2016, 05:48

I try to simulate tig welding in fluent. when i do the simulation using 2D model, the induced temperature on top surface reached close to 4500K. but it is not the realistic value compared to published article. i took material property of 304 stainless steel, current 200A, voltage 14. how to trouble shoot this ? published articles reported the peak temperature of 2500K max. melting point is 1723K.

Try to find the reason for the difference.

Think about what could cause a difference. Think about what you can check. Eliminate things. Find out more. Do research...

If you are a research scholar, then surely you must have done some investigation before in your career? This does not sound like a Fluent question, but more like a "how should I do my job" question...
