Closed volume pressure rise with temperature rise -- CFD Online Discussion Forums

January 11, 2016, 01:04	Closed volume pressure rise with temperature rise	#1
vinayak4399 New Member vinayak Join Date: Oct 2013 Posts: 19 Rep Power: 12	Hi, I am trying to do isochoric compression CFD simulation in Fluent, i.e. a closed domain initialized with air, density as ideal gas law, zero static pressure, & 300 K temperature. I have defined constant energy source so as to increase air temperature, Now I want to observe rise in static pressure with temperature change. But while simulating I observe change in density & obviously in mass in closed domain instead of pressure rise. How can mass of air changes for a closed domain without any outlet? Please help me to sort out this issue. Thanks
