Aerodynamic Optimization of High Pressure Cylinder Inlet Structure of a 300MW Unit
The aerodynamic optimization of high-pressure cylindrical inlet structure of a 300MW steam turbine was carried out by numerical simulation.The flow rate was reduced by increasing the flow area of key parts and the transition inversion.The total pressure loss was reduced from 4.11%to 0.045%,and the outlet static pressure ununiformity was reduced from 0.67 to 0.020.
