Abstract

Condensation occurring in low-pressure stages of steam turbines contributes to many losses in efficiency. Condensation is changing the vapor phase to the liquid phase due to pressure and temperature below saturation. This research aims to simulate the condensation at the last stage of the steam turbine to understand the phenomenon with blade spacing variation. Numerical simulation was conducted by using CFD Fluent. The expected result is that the greater the distance between the blades, the smaller the chance of condensation. It is evident at the P = 91.74 spacing variation has a minimum pressure 22kPa and the lowest droplet growth rate of 1212.663 microns/s.
