| Abstract: | Heat transfer enhancement techniques [active techniques
(electric field, acoustic or surface vibration, etc.) and passive
techniques (fluid additives or special surface geometries)]
can improve performance of heat exchangers to perform a certain heat
transfer duty. Curved tubes have been used as one of the
passive heat transfer enhancement techniques and are most widely used
tubes in several heat transfer applications. This paper
reviews heat transfer through helical coil of circular cross sections in terms
of different dimensionless numbers, their validity, and
effect of geometry, friction factors, different coil curvature ratios, fluid
types, laminar and turbulent flow on heat transfer rate. |
