Comparison of heat transfer rates between a straight tube heat exchanger and a helically coiled heat exchanger
TL;DR: In this paper, the relative advantage of using a helical coil versus a straight tube heat exchanger for heating liquids was investigated. But the particular difference in this study compared to other similar studies was the boundary conditions for the helical coils, whereas most studies focus on constant wall temperature or constant heat flux.
