Particle separators for turbomachines and method of operating the same

A particle separator comprising:

• a separator body configured to be disposed in a first fluid passageway of a machine that directs a fluid carrying particles along a flow path in the first fluid passageway,
• the separator body including plural undulating sections separated from each other by diversion passages, the undulating sections of the separator body positioned to separate a diverted portion of the fluid from a particle-carrying portion of the fluid, the diverted portion of the fluid flowing around and through the diversion passages to a second fluid passageway of the machine while the particle-carrying portion of the fluid flowing over the separator body, past the diversion passages, and continuing to flow in the first fluid passageway.

A particle separator comprising:

• a multi-part separator body configured to be disposed in a first fluid passageway of a machine that directs a fluid carrying particles along a flow path in the first fluid passageway between a radially inner wall and a radially outer wall of the first fluid passageway,
• the multi-part separator body including a radially inward group of undulating sections and a radially outer group of the undulating sections, the undulating sections in each of the radially inward group and the radially outer group separated from each other by diversion passages shaped to separate diverted portions of the fluid from a particle-carrying portion of the fluid, the diverted portions of the fluid flowing around and through the diversion passages in the radially inward group to a second fluid passageway of the machine and flowing around and through the diversion passages in the radially outer group to a third fluid passageway of the machine while the particle-carrying portion of the fluid flows between the radially inward group and the radially outer group, past the diversion passages, and continues to flow in the first fluid passageway.
