Thermal performance augmentation in round tube with louvered V-winglet vortex generator

Pongjet Promvonge et al.

Summary: The article investigates the effect of insertion of louvered V-winglet (LVW) vortex generators on convection heat transfer and pressure loss in a tubular heat exchanger. The experimental result shows that among the LVWs, the case of R-P=0.5, theta=10 degrees provides the largest friction factor and Nusselt number.

Thermal-hydraulic performance in a tube with punched delta winglets inserts in turbulent flow

Jiangbo Wang et al.

Summary: The punched delta winglet (PDW) was found to enhance local heat transfer efficiency while slightly affecting overall heat transfer coefficient and reducing pressure loss in the channel. Among holes with the same area, the larger width and lower height of the hole resulted in the highest thermal enhanced factor (TEF).

Influence of a novel serrated wire coil insert on thermal characteristics and air flow behavior in a tubular heat exchanger

Teerapat Chompookham et al.

Summary: The experimental study involved the insertion of a novel wire coil turbulator, referred to as serrated wire coil (SWC), into a tube heat exchanger to enhance heat transfer performance. Results showed significant improvement in heat transfer efficiency with SWC inserts, supported by developed empirical correlations with acceptable error margins.

Thermohydraulic performance and entropy generation in heat exchanger tube with louvered winglet tapes

Pongjet Promvonge et al.

Summary: This study investigates the thermohydraulic performance, flow friction, and entropy generation analysis of a heated tube with louvered winglet tape inserts. The results show that different louver angles and pitch ratios have a significant impact on heat transfer rates and friction losses. Decreasing Reynolds number, pitch ratio, and louver angle can reduce entropy generation.

Experimental investigation of performance improvement of double-pipe heat exchangers with novel perforated elliptic turbulators

M. E. Nakhchi et al.

Summary: The study explored the heat transfer and thermal efficiency of double-pipe heat exchangers with novel DPIE turbulators. Results showed a significant increase in heat transfer by disrupting the thermal boundary layer using perforated vortex generators. The DPIE turbulators demonstrated higher thermal efficiency and straightforward installation with lower manufacturing costs compared to conventional designs.

Enhanced thermal performance in tubular heat exchanger contained with V-shaped baffles

Pongjet Promvonge et al.

Summary: The study experimentally examined the influences of V-shaped baffle vortex generator inserts in a heated tube, showing that increasing the relative baffle blockages leads to a significant increase in friction factor and heat transfer, while reducing the baffle pitches decreases them. The optimal thermal enhancement factor is found at P-R = 1.0, B-R = 0.15.
