nozzle in fluent
Hi,
I'm simulating a convegent divergent nozzle in fluent with air. I've noticed that the AreaAvarage pressure in inlet changes when I change the dimensions of the nozzle, even if I set as BC ambient pressure inlet; why does that happen? Otherwise I'm searching for the minor pressure drops from inlet to outlet, and I don't undestand why pressure drops seems that have more than one minimum value if I modify the length of the nozzle without changing the angles, but in theory pressure drops should be linear. Does anyone know what I'm probably missing? thank you very much. |

Area Average concept is based on surface area...please check fluent documentation. |

The area-weighted average of a quantity is computed by dividing the summation of the product of the selected field variable and facet area by the total area of the surface.. check this link http://aerojet.engr.ucdavis.edu/flue...g/node1199.htm sudhir |

Thank you for your help. |
Node or mass weighted average would be a better choice in my opinion. Hope it helps..
