binary diffusion coefficient
Dear my friend ~ recently . i wrote a lot of the FLUENT's code to encounter great difficult . Who can help me to solve this trouble ??
My model includes two sepecies(respectively hydrogen ĦB water vapor ) i must write a subroutine to modify the binary diffusion coefficient on my program . Dij(x,y)=3.64e-8*((Pci*Pcj)**0.33)*((1/Mi+1/Mj)**0.5)/((Tci*Tcj)**0.4826)/P Dij(x,y)--pseudo binary diffusion coefficient of species i in mixture j (m2/s) Pci or Pcj-- critical pressure of species i or j(Pa) Tci or Tcj-- critical temperature of species i or j(K) Mi or Mj -- molecular weight of i or j (kg/mol) .............. |

I can try to solve this problem..But you have to say me how you follow a procedure to enable species transport in mixing tanks.. I find transport even if i patch the whole tank with. same mass fraction. Regards Duraivelan.D

Re: binary diffusion coefficient
ok !!~~ you can explain a detail request to me . thanks for your help . .. . As i suggest , you can write a program to finish this subject ..
