Many aspects of turbocharger performance can be and are readily identified through performance testing. Although, when performance is less than satisfactory, test cell mapping only identifies secondary or tertiary troubles which demonstrate inconsistencies with expected performance. Such tasks as seeking out and eliminating efficiency losses or increasing operational surge margin are unrealistic expectations when basing your conclusions solely on inlet and discharge operating conditions. Identifying the root cause such as a mismatched impeller/diffuser or a poorly matched rotor/stator requires a complete aerodynamic analysis employed through a systematic investigation. Turbomachinery design and analysis software predicts the interactions of a working fluid with its geometrical surroundings and operational environment. Accurately predicting these interactions highly depends on understanding the energy loss models embedded within the design code. These loss models dictate how severely performance is diminished due to inherent or sometimes improper geometrical and operational constraints. Such energy losses include skin friction, excessive pressure recovery airfoil incidence, flow recirculation, and blade tip leakage to name a few. Working with aerodynamicists, Globe Turbocharger has fully integrated multiple centrifugal compressor and axial turbine performance codes into its design procedure. This procedure outlines a system of embedded relationships between component geometry, efficiency, performance margin, and on-engine operation. Combining detailed aerodynamic analysis with a systematic design methodology provides the turbomachinery designer and turbocharger end user a system wide perspective of how and why the turbocharger will perform under all operating conditions.
