Abstract

A particle separator for a turbomachine includes a first portion including a first end and a second end opposite the first end. The turbomachine includes a first wall and a second wall defining a primary fluid passage. The first wall further defines an auxiliary fluid passage. The first end is coupled to the first wall. The second end extends from the first wall into the at least one primary fluid passage and extends in a direction defined by the fluid flow through the primary fluid passage. The second end and the first wall define a fluid diversion passage coupled in flow communication with the primary fluid passage and the auxiliary fluid passage. The fluid diversion passage is configured to divert fluid from the primary fluid passage to the auxiliary fluid passage in a direction at least partially opposed to the fluid flow through the primary fluid passage.
