I am using OpenFoam tool for simulating Two phase Flow problem using InterFoam. I get good results when I used ratio of dynamic viscosity (mu1/mu2=1,20,100)but when I used actual value (Lead lithium = 0.0000000394*9926 (nu*density) and helium=.00108823529*0.034), I am not getting results. Anybody knows what is the problem? plz see the file attached for velocity profile

It seems to me your lead viscosity is 10x smaller than it should be. Furthermore, your post is of very poor quality. Label the axis on your image, and properly describe why the result you are getting is not what you expect. Read this post:

sorry for poor quality of post.
I used kinematic viscosity of lead lithium as 3.94*10-8.
I had attached the validation results when viscosity ratio of two fluid is 5.37 (viscosity ratio 5.37 mean I take one fluid's viscosity as 1 and other as 5.37 (fictitious fluid)) and it quite matches with the results publish in research paper.
but when I used actual value as mention in above post, I get stiff gradient in lead lithium side and then velocity become almost zero and again get parabolic curve for helium.
I am not sure that above results good as shown in attached file velocity profile and alpha. I am expecting the results as in attached file image.
