modelling a low pressure gas in a cylinder for thermal analysis
modelling a low pressure gas in a cylinder for thermal analysis
(OP)
hello
I want to study the temperature variation in a very low pressure gas where radiation is the major mode of heat transfer and convection can be neglected.in the cylinder heat is continuously emitted by a hot plate which is placed at one end in the cylinder.how can i model this nx nastran solver in thermal environment.?

RE: modelling a low pressure gas in a cylinder for thermal analysis
THEN solve it roughly by hand.
And don't "ignore" convection! You don't "know" yet if anything can be ignored! (Unless this is a homework assignment.)
THEN show us how you have entered your estimates into the FEA program.
Garbage in = garbage out. Only faster.
