hi
it is the tenth time i wrote this thread here...
i thinkthis is not a scientific forum...... all my posts remain unanswered..
tell me please , i have to model suction over flat plate in fluent
i need validation case...
i need the flat plate length,number of holes,diameter of hole, free streem velocity,suction velocity, the location of the first and last hole,,,
i have found some articles, but there is no sign of the above-mentioned parameters there...

hellllllllllllllllllllllllllllllllllllllllllllllll llllllllllllllllllllllllllllllllllllllllllllllllll lllllllllllllllpppppppp

Why don't you do a search for previous scientific journals that report past experiments?

hi thanks for your response
i did it.....i read so many articles but i could not see the parameters i need there....

Do the papers mention mass flow rate at all? If the mass flow rate and hole diameter are given you can calculate the amount of mass leaving the main flow (through the suction holes) and thus your required velocity inputs.

I think you are looking for boundary conditions? In the case of suction plates, might some of them be porous materials, which is why you aren't finding specific hole diameters and locations?

What variables are given in the papers you are looking at?

my point is that there must be given conditions in the papers you are reading, otherwise I don't think they would be published.

The point of publishing papers is so that other researchers in your field can also verify your results. Without values they would not be able to do this.

Is it possible that you don't know how to interpret the published results? If so you could put a link to the paper on here and see if someone else could help you set up your boundary conditions.
