Recently, the use Nano-fluids fact that suspension stability Nano-fibers and the nanoparticles are solid, as a new strategy Heat transfer operations has been proposed .Recentresearch on Nano-fluids, by Comparison a significant increase in thermal conductivity Top of Form with liquids without nanoparticles orwith larger particles Other differences between this type of fluid would be identified, citizenship severe thermal conductivity of temperature increase in allowance Flaks critical thermal heat transfer course the reactions to them. Experimental results obtained from Nanofluidsbe obvious that the results Example can be cited Heat with existing theories. This shows the lack of guidance increases the ability ofmodels to predict properties Nano-fluids is correct .So to use this type of fluid in the future And at the new systems, should take action todesign and create models and include the effect of volume ratio and fluidity of nanoparticles and correct factors related to it.
