In this study, 3-D numerical simulations were carried out to analyse the influence of
geometrical parameters for eight spirally inner corrugated tubes at turbulent flow (R e= 25× …

A novel twisted annulus between two counter-twisted oval tubes is proposed for a double-
tube heat exchanger. The oval tubes of the annuli have same twist pitch, but twist with …

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 …

A double pipe heat exchanger with outward helically corrugated tube is numerically studied
and optimized. Under the determined geometry parameters of the corrugated tube, the …
