Opening soon the exhaust valve "sonicTurbDyMEngineFoam"
Hi every body,
I have a problem with a case for coldFlow in an internal combustion engine (sonicTurbDyMEngineFoam )....the exhaust valve opens early (about 0.005 (s) ).Can any one help me???? How do I correct it??? thanks, Sasan |
Greetings Sasan,
Can you please provide more information? The reason I ask is because you're not providing enough information, as indicated in this thread: http://www.cfd-online.com/Forums/ope...-get-help.html Best regards, Bruno PS: don't mind about the other post with strange characters, it was just a spammer... |
Opening soon the exhaust valve "sonicTurbDyMEngineFoam"

Hi wyldckat ,
Thank you very much. I am running a case that it simulates the cold flow in an internal combustion engine. The solver is sonicTurbDyMEngineFoam.The rotational velocity is (rpm=1500), So the total time for a cycle of the engine is 0.08(s).I expect that the exhaust valve opens at 0.06(s) but when I plot the mass flow versus time at the exhaust port I saw that the exhaust valve opened at 0.055(s).How do I can correct this problem???please any one help me.... The engineGeometry is as below : Code:

The exhaust will open when the lift exhaust valve lift exceeds 0.0025 as specified in your dictionary.
So it depends on your valve lift profile. cheers peter |
Thanks for your reply peter,
Can you give me any sources about describtion of minimum valve lift and valve lift profile?? Can you explain them?? thanks, Sasan. sasanghomi@yahoo.com |
hi, i have a problem with this solver too. The error is:
