A multi-condition spectral proper orthogonal decomposition approach for reconstruction of transient temperature fields in turbine blades

•A multi-condition SPOD method is developed for transient field reconstruction.•Frequency-aware SPOD modes are extracted from five types of thermal scenarios.•Reconstruction is performed under unknown inlet conditions using sparse sensors.•SPOD modal coefficients are estimated via compressed-sensing...
