Transonic Fan Optmization

Saima · September 14, 2012, 12:15

Hello Guys,

I have a quick query: Regarding Transonic Compressor Fan optimization. I am doing Aerodynamic optimization for compressor fan but have a problem to set back pressure.

When Fan shape is changed during optimization the back pressure no more good for new blade shape. As one of the constraint for optimization loo is to have 0.5% diff of mass flow rate. But because P2/back pressure no more good so it is not able to get mass flow rate tolerance.

Do you have any clue or idea to set that.

Regards,

i need the geometry if u can help me ,, how u can get the geometry ?? are u using vista AFD

For geometry creation we have our in-house software.
