mass diffusion coeff. of water-liquid
 
hi cfd's

can anybody tell me the value of mass diffisivity of WATER-liquid? I am using water-liquid as tracer in a tank containing water-liquid (both having same properties). Hence i am need of numerical value of mass diffusivity of water-liquid in water-liquid.(K-e turbulence model) thanks in advance. bye l.g.patil

hi i have read it but, somehow my fluent answers are not matching with expt data. trend is ok but other characteristics are matching. i am expecting some problem related to diffusion coeff. if you have any other ref. pl convey at the earliest. presently i am using mass diff of mixture( water- water) as 3.0e-9 bye

hi! The other characteristics, which are not matching correctly...they are dependend on the mass diffusivity? I mean, there are so many things to define, you think mass diffusivity is the one which is wrong? Yvonne
