Abstract [en]

Compressors operating range is limited at low mass flow by the development of surge. The objective of this research is to study effective operational range for a turbocharger ported shroud compressor typically used in diesel engines. Surge characteristics are assessed by planar flow measurements in the vicinity of the compressor inlet along with numerical computations in the entire compressor geometry. In this paper, satisfying characterization of the compressor instabilities was achieved. Experimental measurements yielded a better understanding of the flow interactions occurring at the compressor entrance and the validation of the computational results in stable regime for this specific model.
