Hi, my problem is to use fluent to determine a fan charateristic curve (flow rate vs static pressure) for a specific fan (exhuast fan). I have used GAMBIT to create a 1/6th section of the fan, which comprises one blade of the fan... I want to use the unsteady solver/moving mesh options in FLUENT... I also plan to use grid-interfaces between fluid volumes (fan to duct, etc)... how would I set up the problem and boundary conditions to solve for a number of flow rates and determine the static pressure rise in each case.

hi, i did my M.E project , determining the fan characteristic curve using CFD. urs srinivasan

Hi,

I am also interested in a similar thing. How did you do that srinivasan?

Hi srinivasan, that sounds exactly what I want to do, any pointers??

Moke, how much have you looked into this problem?? Maybe we can offer each other the solution.

Could you reply me to my email at munni29@yahoo.com. I need some help in the fan curve simulation.
Thanks.

Hi I am quite new to CFD i am trying to find out the fan curve what did uptill now I made inlet duct 15 times of fan dia with pressure inlet (0.0 Pa), outlet duct 30 times of fan dia with pressure outlet (0.0 Pa) and I am giving fixed rpm to the rotating region in between. I am measuring pressure in inlet and outlet duct at a position 10 times of fan dia. but Still I didnt find the relevant pressure difference across the fan and also the solution is not converges

I would be very grateful if you people help me out
