At top of cavity ,what suitable ambient condition (temperature, heat transfer coefficient) should be usedIMG_20220113_094331_584.jpg

Until you explain what you are modelling and why I can only guess.

Geometry (20 x 20 x 2.7 )cm similar walls cavity filled with glass . Heat flux from bottom ,top to ambient condition and other walls is adiabatic

What question do you want to answer when doing CFD?

What suitable ambient condition (temperature, heat transfer coefficient) should be used on top

That is just a boundary condition.
But why do you do simulation? What physical question do you want to answer?

i need value of heat transfer coefficient at room temperature
