The Numerical Simulation of Air Helical Flow Outside of Upright Tube
The coefficient of heat transfer is comparatively low on the condition of forced air convection. The air helical flow in the shellside can improve the heat transfer coefficient of air forced flow and bring lesser pressure loss. This paper introduces the simulation of air helical flow outside of upright tube with the software PHOENICS on the expeimental work condition. Based on the reasonal simplification and model building, the distribution of temperature field, velocity field and pressor field are simulated and analyzed. The distribution of the simulated fields are rational with the practical conditions. The error of simulation result is lower to 10％ compared to the experimental results. It could be a effective method to analyze the heat transfer and flow resistance in the helical baffle heat exchanger.
