چکیده:

This study is considered the heat transfer behavior of aqueous suspension of multi-walled carbon nanotubes under constant heat flux. We measured heat transfer coefficient of CNTs nanofluid in laminar flow regime. A considerable enhancement in convective heat transfer coefficient of nanofluids is observed, and it was especially significant in entrance length. The increment depends on the CNTs concentration and flow condition (Reynolds number). In addition, it is a function of axial distance from inlet and it has a decreasing trend.
