Heat transfer and friction factor characteristics in turbulent flow through a tube fitted with perforated twisted tape inserts (2013, unknown): “Some experimentswere performed to obtain heat transfer enhancement in a tube using delta-winglet twisted tapes [5].”
Heat transfer enhancement in a tube using rectangular-cut twisted tape insert (2013, methodology): “These higher values of fe than fs are due to the high viscous loss near the wall regions caused by swirl flow, Eiamsa-ard et al., 2010b. Figure 6 also shows the friction factor obtained from Petukhov relation, fth. Fth were found to be significantly lower than fs. Enterence effect could be the…”
Enhancement of heat transfer using CuO/water nanofluid and twisted tape with alternate axis☆ (2011, methodology): “modified twisted tapes were employed with water (base fluid) and it was found that the heat transfer enhancement depended strongly on their shapes and geometries [11–24].”
Numerical studies on heat transfer and flow characteristics for laminar flow in a tube with multiple regularly spaced twisted tapes (2012, methodology): “[15] experimentally studied the heat transfer, flow friction and thermal performance factor characteristics in a tube fitted with delta-winglet twisted tape, using water as working fluid.”
