Dear Ahmed Ramadhan Al-Obaidi

Take a look at my last published article and read the introduction section. It may help.

Good luck.

Mustafa Al-Dulaimi

Dear Dr Ahmed

The effect of nano particles can be modelled using single phase models. The fluid physical properties are modified by using empirical correlations.
