October 24, 2016, 01:44	Exhaust Gas Re circulation Model	#1
sumant New Member Sumant Morab Join Date: Oct 2016 Posts: 1 Rep Power: 0	Hi everyone, I have designed 2D model for Combustion chamber with 2 egr pipes. But after the calculation, I observed in the results that instead of exhaust gas moving in pipes, fresh air is moving in upward direction. I tried patching some region in pipe with negative velocity but again fresh air was moving upwards instead of exhaust gas coming downwards. Please help me so as to avoid upflow of air in pipes. setup- Steady, non-premixed combustion, pressure-based
