Effect of Twisted Slice on Fluid Dynamics Performances of Fluid Media in Cracking Furnace Tube

Abstract:

Employing air at normal temperature and pressure as fluid media, the effect of twisted slice on fluid dynamics performances of fluid in cracking furnace tube was studied. The experimental results showed that boundary layer in cracking furnace tube fixed with twisted slice became thin, which leaded to the increase of heat transfer coefficient. So heat transfer was enhanced. Axial velocity distribution in central area of the tube fixed with twisted slice was smoother than that of circular tube, while velocity grad in near wall area was greater. Pressure drop increased in the tube fixed with twisted slice, whereas pressure distribution was even along axial length of the tube, in agreement with the pressure distribution in circular tube.
