Evaluation des termes temporels permettant de décrire les transitoires rapides d’un turbocompresseur de suralimentation automobile

Abstract : The document presents the results of an experimental work devoted to create pulse flows, independently from a real car engine, equivalent to the exhaust pipe engine flow characteristics, on the overall performances of a turbocharger. A comparative analysis on existing test stands that are able to perform such flow conditions is presented. This allows defining a new test stand which specific conditions that are not already covered by previous test stands. All steps concerning the ability to set up of the new test stand and more specifically instrumentation development and acquisition systems are detailed. First set of results obtained with the test stand, in pulse conditions, are presented with some analysis on performance comparisons between steady and pulse inlet conditions at the turbocharger inlet section. The new pulse test stand allows performing more flexible variations of inlet flow unsteady conditions, different thrust load values and number of motor cylinders as well
