The changes of three key structure parameters entrance angle (θ), clearance of inner high end (L),distributor height (H) on the average velocity and the flow uniformity of the shellside vertical section and the entrance section after the steam enters the shellside were studied by means of computational fluid dynamics method. The results showed that flow uniformity after medium enters the shellside was actually improved by changing the structure parameters θ, L, H, which influence flow area. Considering the flow uniformity of the shellside vertical section and the entrance section, the optimized parameters which make the shellside flow uniformity are θ=9°~21°, L=100~120 mm, H=204~216 mm.The changes of three key structure parameters entrance angle (θ), clearance of inner high end (L), distributor height (H) on the average velocity and the flow uniformity of the shellside vertical section and the entrance section after the steam enters the shellside were studied by means of computational fluid dynamics method.
