TL;DR: In this paper, the effect of flow velocity on the calcium carbonate fouling in smooth tube was investigated and the results indicated that fouling has two aspects regarding the effects on fluid flow as well as thermal performance of the heat exchanger in the induction period: an increased surface roughness, and followed by the decrease in metallic surface area of the test tube as fouling progresses.

TL;DR: In this article, the heat transfer of circle tube bank fin heat exchanger with VGs or without VGs on the fin surface having ten different configurations (different fin spacing, height and attack angle of VGs) was numerically studied.

TL;DR: In this paper, the effects of fin pitches and tube diameters on the air side heat transfer performance of a tube bank fin heat exchanger using curved delta-winglet vortex generators were experimentally investigated, and the counterpart plain fin was selected as a reference for optimizations of fin geometries.

TL;DR: In this article, a combination of wavy fins and vortex generators is proposed to optimize the thermal performance of heat exchangers, and the effects of the longitudinal vortices and attack angle of the vortex generators on thermal performance are numerically studied.

TL;DR: In this article, the relationship between the intensity of the secondary flow and laminar convective heat transfer was studied using a numerical method, and it was shown that the cross-averaged absolute vorticity flux in the main flow direction can reflect the intensity intensity of secondary flow.
