Turbocharger Performance Measurement

The bachelor’s thesis deals with recent methods of measuring turbocharger characteristics. Besides an introduction to fundamental performance characteristics, such as compressor map and turbine map, thesis contains description of experimental methods of collecting such data, which is essential for designing a turbocharged power unit. Description of main parts of the test stands and limitations consequent upon the measuring methods is supposed to offer basic knowledge of turbocharger design validation to the reader. As an extension overview of tests increasing accuracy of these characteristics and a few additional and safety tests is presented. Examples of use of these characteristics in engineering calculations should give an image of significance of creating computational model from experimental collected data, which describes thermodynamics of the turbocharger
