EGR mixing case -- CFD Online Discussion Forums

rajeev50588 New Member Join Date: Feb 2013 Posts: 10 Rep Power: 13	Hiii.. In this case i am simulating air and EGR mixing in this nozzle. i am not willing to give mass flow inlet for EGR (although i have mass flow rates for EGR1 and EGR2 inlets). I want to drive the EGR due to pressure difference in this convergent divergent nozzle. I have attached the BC's i want to simulate. Would like you to help me with the what exact BC's to be used. If i give mass flow then pressure dsnt matches and vice versa.I have used the following BC's but of no use a) Inlet - Mass flow , EGR's inlet - stagnation inlet, Outlet - Pressure outlet b) Inlet - Stagnation inlet, EGR's inlet - Pressure outlet ( with target mass flow) , Outlet - pressure outlet Physics i have used are as follows: Ideal gas, K-e turbulence, passive scalars, segregated temp, segregated energy, all y+ etc Help me out with this Regards RD egr case1.JPG
