"In this study heat transfer in a vortex flow has been investigated experimentally and analyzed qualitatively.
Air was forced through a Ranque tube in order to get a swirling turbulent flow in its "hot" section. The test section, having a diameter of .355 inches and a length of 27.5 inches, was heated by an induction coil.
Three types of flow were under investigation: a linear turbulent flow, a vortex uniflow and a mixed vortex-linear turbulent flow.
The experiments covered a range of tube-wall temperature from 570 to 900 Deg. R and inlet pressure to the vortex generator ranged from 25 to 110 psia. Reynolds numbers for the linear turbulent flow ranged from 10000 to 160000. Heat fluxes ranged from 1000 to 19000 BTU/hr.sq.ft.
The experimental results indicate a considerably higher inside surface heat transfer coefficients for the vortex uniflow than those for a linear turbulent flow of air at the same mass rate of flow"--Abstract, page 1.
