2014年1月1日 · We evaluated the axis ratio effect on the overall thermal–hydraulic performance of elliptical finned-tube heat exchangers using a proposed CFD model which can simultaneously predict the fluid flow and heat transfer on both air-side and water-side.

2024年11月1日 · Tubes with elliptical, flat, or circular shapes are typically arranged in either inline or staggered patterns. The extensive use of fins in tube banks is due to the fact that 85 % of the governing thermal resistance is experienced by the fluid flowing over the tube banks [3].

2019年5月1日 · The effect of fluid velocity, tubes arrangement, tubes rows, tube spacing, fin spacing, shape of tubes on the heat and flow performance has been investigated. This paper discussed the circular tube and the elliptic tube.

Elliptical Finned Tube is an elliptical seamless tube as the base tube, which uses aluminum fin strips or copper fin strips to spirally and tightly wrap around the outer surface of the base tube under tension.

2020年9月7日 · In this study, thermo-fluid characteristics of elliptical annular finned tube heat exchanger were numerically studied in detail. Transition SST model was utilized to simulate turbulent flow. Effects of air velocities, horizontal to vertical fin diameter ratios, and fin densities were examined in detail.

Elliptical Finned Tube is an elliptical seamless tube as the base tube, which uses aluminum fin strips or copper fin strips to spirally and tightly wrap around the outer surface of the base tube under tension.

2023年9月1日 · Improving the thermal hydraulic performance of wet gas can greatly improve the energy utilization rate. The thermal hydraulic characteristic of finned elliptical tubes with different...

Elliptical finned tubes are used in heat exchangers to supply hot air or transfer heat to the drying cylinders. They capture heat from exhaust gases or other heat sources and use it for preheating air or water, optimizing energy usage in paperboard mills.

Elliptical Finned Tube is a type of tube used in heat exchangers that have an oval-shaped external fin. Secondly, the fins are usually made of materials such as aluminum or copper and are wrapped around the base tube in a spiral or helical pattern.
