Abstract: Abstract:Using the fluid simulation software AFT Arrow, the steam leakage pipe model of steam turbine shaft seal was established. The flow setting method and the pressure setting method were used to calculate the steam leakage rate of the shaft seal respectively, and the features of the two calculation methods were analyzed. The calculation results can be used as reference for the turbine manufacturer in shaft seal system design and for the design institute in optimization of piping layout.
