Heat transfer with laminar pulsating flow in a channel or tube in rolling motion

The heat transfer model of laminar pulsating flow in a channel or tube in rolling motion is established. The correlations of velocity, temperature and Nusselt number are obtained. And the effects of several parameters on Nusselt number are investigated. The results are evaluated with Nield & Kuznetsov's work. It is found that Nield & Kuznetsov's results are not applicable for the laminar pulsating flow in nuclear power systems in ocean environments.
