Effects of leakage vortex on aerodynamic performance and loss mechanism of steam turbine
Proceedings of the Institution of mechanical engineers. Part A, journal of power and energy, 2019 To avoid friction, a clearance between the rotor blade tip and the cylinder is needed in a steam turbine. As a result, the leakage flow is formed under the pressure difference which mixes with the main flow and causes the mixing loss.
