^aGeometric position accuracy of thermocouple position coordinates is estimated at ±1.5%.
^bFor nominal inlet pressure 225 psia (1.55 MPa), 80°F (700 K), and 3% combustor pressure drop.
^cNote: Col C, G, F, K, M, Q, V, and T are data set tracking identifiers.
^d𝑋=𝑥/𝐿 (which varies from 0 to 1), where 𝑥 is the TC position measured from the liner inlet and 𝐿 is the overall liner length.
Θ= circumferential TC position measured over the liner outside 𝑦/𝐿_𝜃 (0 to 1) and continuing back along the inside liner (1 to 2), where 𝐿_𝜃 is half the unwrapped liner “width.” The normalized unwrapped coordinate (𝑋, Θ) is the TC location (𝑥,𝑦).
