Spatial Flow-Field Approximation Using Few Thermodynamic Measurements Part I: Formulation and Area Averaging
A regularized Fourier-plus-polynomial regression reconstructs 2D engine temperature fields from sparse rakes, and the integrated area averages differ from the standard sector-weighted averages by 0.5 to 2 K.
