Thermal expansion coefficient

MFiX
#1

Hello

How can I define the thermal expansion coefficient for natural convection problem?

Hi Samah. Iā€™m fairly certain that none of the MFiX models handle thermal expansion. Can you tell us a bit more about what you are trying to do?

I am trying to simulate the natural convection in a partially heated rectangular enclosure, I need to add the body force term in y-momentum equation highlighted in the red box.

Looks like a duplicate of Define body force term in y-momentum equation

Please see my answer at the bottom of this post.

Dear Jeff,

Thank you so much for your response. I believe I phrased the question in the improper way. I posted my question another way.

I am sorry for asking a lot. I am a beginner and a little bit confused and facing difficulty deciding how to proceed.
