Heat Transfer and Flow Behaviors of Ferrofluid in Three-Start Helically Fluted Tubes

Numerical Analysis of the Pulsating Heat Transfer of Ferrofluid in Helically Fluted Tubes

“…Next, Mucci et al [53] numerically investigated pulsating flow behaviors inside the heat pipes. For the experimental study, the most transient nanofluid flowing through in the various flow channel configurations are analyzed [54][55][56][57][58][59][60].…”

“…The experiment cannot be analyzed and/or predict the flow behaviors near the boundary layer zone of the corrugated tube, which results in the heat transfer enhancement, while the computational study can be performed to find better the heat transfer and flow behaviors. The previous works [54][55][56][57][58][59][60] experimentally studied the pulsating heat transfer characteristics using nanofluid flowing in the spirally coiled tube [54,55], in the corrugated tubes [56], in the micro-fin tube [57], and in the fluted tube [58,59]. While the flow and heat transfer characteristics of nanofluid flowing in the fluted tube for the continuous flow are predicted by Siricharoenpanitch et al [60] and compared with the measured results [58,59].…”

“…However, they do not consider the flow behavior for the pulsing flow. Therefore, the current work is continuously performed from those studies [54][55][56][57][58][59][60] in which the numerical analysis of pulsating ferrofluid flows in the fluted tube. As the results from the previous work [5] show, the Eulerian two-phase turbulent modeling gives the highest accuracy compared to the measured data.…”

“…As the results from the previous work [5] show, the Eulerian two-phase turbulent modeling gives the highest accuracy compared to the measured data. Therefore, the two-phase model is used to evaluate the temperature behaviors of ferrofluid with different pulsating flow frequencies flowing through the fluted tube, which the obtained are validated with the experimental results [59,60].…”
