Dear @anazarahari , thank you for your reply. I checked the paper and also I am reading your interesting paper. As you said, the idea behind this technique now is making more sense to me.
However, for the calculation part, I am not sure of the conversion factor. I am using the same technique as described in here,but I am not sure if this is a correct way to convert the obtained TC from real units to W/(m.k). Could you also comment on this part if possible for you?
Thanks,
Mahsheed
