Temperature sensor assembly for swirling flows

A temperature sensor assembly comprising:

• a bluff body including a first concave surface and a second concave surface, said first concave surface and said second concave surface tapering to a trailing edge;
• a first member spaced apart from said bluff body, said first member including a convex surface and a concave surface extending downstream from said convex surface of said first member;
• a second member spaced apart from said bluff body, said second member including a convex surface and a concave surface extending downstream from said convex surface of said second member;
• and
• a sensor element spaced apart from said bluff body and disposed at least partially between said first member and said second member.

A method of operating a temperature sensor assembly, said method comprising:

• mounting the temperature sensor assembly within an aircraft engine that generates a fluid flow, the temperature sensor assembly comprising:
• a bluff body;
• a first member spaced apart from the bluff body;
• a second member spaced apart from the bluff body;
• and
• a sensor element spaced apart from the bluff body and disposed at least partially between the first member and the second member;
• channeling a portion of the fluid flow between the bluff body, the first member, and the second member, such that the portion of the fluid flow makes contact with the sensor element;
• and
• sensing a temperature of the portion of the fluid flow over the sensor element.
