hi, i am studing about impinging air jet. i have a 2D model. but, fluent gives me "reversed flow" warning for all iteration. i have tried so many mesh structures, I extended my geometry but I couldnt solve this problem. What would you suggest to eliminate this problem?

Try initialising using a small velocity then steadily increase it to the desired value through out the solution.

i have tried initialising using small velocity. reversed flow error disappeared. but after about 500 iteration it appeared again and reserved flow faces increased steadily.

Merhaba MUstafa sanırım benim 2 sene önce yaptığım tez ile aynı konu üstünde çalışıyorsun bende MÄ°nogowa nın impinging jet testini fluentte uygulamaya çalışmıştım matlabdede çıkan sonucları karşılaÅŸtırmıştım ÅŸuan iÅŸteyim ama müsait olursam bu konuda sana yardımcı olmaya çalışırım.

Hi Mustafa and emre,
Could be interesting for somebody in the CFD community to understand your responses. Sorry but I can not understand you if you do not post messages in english. Thank you in advance. |
