Uncertainties in transient heat transfer measurements with liquid crystal
Y. Yan,J. Michael Owen +1 more
TL;DR: In this paper, an uncertainty analysis is used to calculate P h, the uncertainty in h, and P T aw, when T aw is unknown, in terms of the random uncertainties in the measured temperatures.
Journal ArticleDOI
Experimental Measurements of Ingestion Through Turbine Rim Seals—Part I: Externally Induced Ingress
Carl M. Sangan,Oliver J. Pountney,Kunyuan Zhou,Michael T. Wilson,J. Michael Owen,Gary D. Lock +5 more
TL;DR: In this article, the authors describe a new research facility which experimentally models hot gas ingestion into the wheel space of an axial turbine stage and assess the performance of two generic (though engine-representative) rim-seal geometries in terms of the variation of concentration effectiveness with sealing flow rate.
Journal ArticleDOI
Prediction of Ingestion Through Turbine Rim Seals—Part II: Externally Induced and Combined Ingress
TL;DR: In this paper, the orifice equations were derived for compressible and incompressible swirling flow, and the incompressibility equations were solved for axisymmetric rotationally-induced (RI) ingress.
Journal ArticleDOI
Transient heat transfer measurements using thermochromic liquid crystal: lateral-conduction error
TL;DR: In this article, an analytical one-dimensional solution of Fourier's conduction equation for a semi-infinite wall is used to measure the surface temperature in transient heat transfer experiments.
Journal ArticleDOI
Transient heat transfer measurements using thermochromic liquid crystal. Part 1: An improved technique
TL;DR: In this article, a more general solution to the one-dimensional conduction equation is presented for a "slow transient", where the rise in air temperature is represented by an exponential series.
