Fluted Helix Channel Heat Transfer along a Vertical Tube
要約
The paper investigates (a) thin film formation and (b) falling film heat transfer along a twisted and fluted helix channel on the surface of a vertical tube. Flow and heat transfer of a single-component liquid on the surface on a fluted helix tube are considered and investigated by both numerical simulation and experimental observation. It is found from the numerical study that in certain parameter regimes, the flow and temperature fields can be solved in a closed form. It is seen from experimental results that thin films can uniformly cover the surface of the tube and possess relatively higher heat transfer coefficient.
