This paper outlines the development of the Turbocharger Component Matching System (TuCMS) software package that can be used to inexpensively analyze turbocharger performance, and match turbocharger components to integrate and optimize turbocharger-engine performance. The software system is being developed with the intent to reduce the time taken to experimentally match a turbocharger with an engine, a task that is key to engine emission reductions. TuCMS uses one-dimensional thermo-fluid equations to analyze both the compressor and turbine side of a turbocharger. The program calculates the velocities, pressures, temperatures, pressure drops, and efficiencies for a specified set of turbocharger geometry and atmospheric conditions. Both the compressor and turbine side include established loss models found in the open literature. Work and rotational speed are the parameters used in the turbine and compressor analysis algorithms to integrate the turbocharger system. TuCMS utilizes a component-based architecture to simplify model enhancements. TuCMS can be used as a cost effective engineering tool for preliminary turbocharger testing during engine upgrades and modifications.
