Dear All I want to ask you that can i optain the value of Flow rate in fluent and how? Regards. Mustafa Ayad

yES YOU CAN SEE THE MASS FLOW RATE USING THE SURFACE INTEGRALS THEN FROM LEFT MENU SELECT FLOW RATE AND SELECT THE SURFACE ON WHICH YOU WANT TO SEE THE FLOW RATE

hai, i have solid and fluid domain meshed and saved in separate .dbs file.

how to merge those two files to build complete model. this is for combined conduction and convection analysis

thank you,

gaurav_fluent · March 16, 2009, 01:56

save both files in meh format and improt in single file

thank you,

Export two msh-files from within GAMBIT. Use Tgrid to merge both msh-files into one or for TUI-fans just use utility tmerge for merging the two msh-files into one. But keep in mind, that the both meshes do not "know" each other. If the surface meshes are identically you might connect (or in fluent: fuse tgrid: merge) them. Otherwise you will have to use coupled interfaces with all their disadvantages.

good evening,I want to ask you if i can optain the value the volumetric mass transfer coefficient in fluent (eulerianeaulerian model and for a single bubble size) and how?
best Regards.

Hi all,
I want to input the volumetric flow rate of air throw the inlet, can that be done or do i have to input the velocity? I am getting weird answers if I input the velocity..
thanks

hi rishab

you can convert the volumetric flow rate to mass flow rate by multiplying volume to density of air. now after it run the case for some iteration and check whether it is giving you the same velocity as you are giving at inlet .

if it is same then there is some other problem, let me know

thanks! i just let the simulation run longer and now it works fine with the velocity..i think the problem before was that i did not let the input air profile develop long enough
