Notas:
Helical-wire-coils inserted in a round tube have been experimentally studied in other to obtain their thermohydraulic behaviour in laminar, transition and turbulent flows. Using water and propylene glycol mixtures at different concentrations, a wide range of flow conditions was covered: Reynolds Number from 100 to 90 000 and Prandtl number from 2.8 to 200. Six Wire coil insets were tested, with a geometric range of helical pitch 1.17 less than p/e less than 33 and helix angle 30º less than infinity less than 53º. Wire coils were tightly attached to the inner tube surface. Experimental correlat...
