aGeometric position accuracy of thermocouple position coordinates is estimated at ±1.5%.
bFor nominal inlet pressure 225 psia (1.55 MPa), 800°F (700 K), and 3% combustor pressure drop.
cNote: Col C, G, F, K, M, Q, V, and T are data set tracking identifiers.
d (which varies from 0 to 1), where is the TC position measured from the liner inlet, and is the overall liner length. : circumferential TC position measured over the liner outside (0 to 1) and continuing back along the inside liner (1 to 2), where is half the unwrapped liner “width.” The normalized unwrapped coordinate is the TC location .
