Reversed Flow on Iterate

August 23, 2006, 03:52

I was ran the model more than 50 time,all problem seen reversed flow condition,i also try use pressure inlet as atmospheric pressure and oulet is o at the gauge pressure,but the problem is same,reversed flow.Hopes anybody can help?My Case study is simulate scavenging process on two-stroke engine.

Where you are getting this reversed flow? If it is near to inlet or outlet, just extend the domain of control volume.

how to make extend the domain of control volume?
