Abstract

The turbulence and flow rate around the specimens were analyzed by Fluent and results indicated that specimens installed in the pipeline varied the fluid flow direction, highly increased the flow rate nearby and formed strong turbulence around the specimens, the max turbulence in work areas could reach 10%. Experiments about the influence of turbulence on corrosion rate showed that max influence of turbulence on average corrosion rate was 15.5% and obviously lower than the max influence of temperature;but in high turbulence areas the influence of turbulence on local corrosion depth was almost equal to the max influence of temperature. The corrosion depth on the specimens was consistent with the distribution of turbulence and the corrosion rate difference in work areas explained why ditches existed in high turbulence areas.
