Design and Heat Transfer Enhancement Study of a New Spiral Groove Tube for Supercritical Methane
It is proposed to use supercritical methane as the work material and spiral fluted tube to achieve the purpose of enhanced heat transfer.It is found that,compared with the spiral light tube,the strength of the secondary flow is enhanced and the heat transfer performance is improved after the number of groove heads and the angle of helix angle of the spiral groove tube are reasonably designed.
