With the increasing high heat transfer requirement of modern industry, it is still an important
issue that how to improve the thermal performance of heat exchangers efficiently. The …

To enhance the fin-side heat transfer capability of circle tube-fin heat exchangers, a novel fin
with ellipsoidal dimple-protrusion is introduced in this paper. The effect of the ellipsoidal …

This study proposes a novel active method, the electromagnetic vibration method, to
augment heat transfer in a heated copper tube. To that end, a stretched wire turbulator with a …

In this paper, simultaneous use of active and passive methods for enhancing the thermal
performance of a double-tube heat exchanger was investigated. This was done by injecting …

The current research deals with an experimental and numerical inspection of the shell and
helically coiled tube heat exchanger (SHCTHE) under various circular, elliptic, and square …

In this paper, the design and thermo-hydraulic performance of a double pipe heat exchanger
with helical baffles in the annulus side, are investigated numerically. Three-dimensional …
