Gas Density Problem

eng_yasser_2020 · May 13, 2014, 10:27

Hi, All

I have a model consists of two concentric pipes and a gas in between. The ambient air surrounding the outer pipe. The inner and outer pipes made of aluminum and have heat sources (W/m3). The analysis will be 2D Planar, Steady state and check the gravity.

Why when i changed the polynomial of gas Density, there is no changes in the temperature profile happens???

Thanks all

Hello Yasser,
can you post a picture of your system? Are you using a conformal or non-conformal mesh?

Regards
