Turbochargers are used to either increase engine power output or reduce air pollutants by increasing the trapped air-to-fuel ratio. An increasing need has arisen for the turbocharger compressor to operate at an ever-increasing pressure ratio while…
The objective of this project was to develop a numerical simulation system that can be used to optimize the performance of a large-bore reciprocating engine. The simulation system will include sub-models of all major components between the inlet…
Turbomachinery that operates in a field environment, such as turbochargers utilized by the natural gas transmission industry, are subjected to environmental conditions that affect machine performance. For example, dust and oil in the atmosphere can…
This report 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…
The objective of this project was to either validate the current correlations or develop a new correlation that are used to compare compressor maps. Most compressor maps are presented at standard temperature and pressure. In order to compare data…
The natural gas transmission industry has used increased air flow technologies to constrain emissions from reciprocating engines to levels at or below those required by regulations. Typically, the engine is turbocharged or, in the case where a…
Turbocharger performance, especially on SIP-call engines, remains essentially unmeasured even though tracking information over time would provide critical information to help field engineers lower their engine emissions as well as the cost of…
The natural gas transmission industry has been subject to increasingly stringent emissions regulations over the years, with tougher regulations yet to come. One of the biggest challenges has been to reduce oxides of nitrogen (NOX) while maintaining…
To develop the requisite air flow rate, the turbocharger must operate at a relatively high efficiency. But as important, the system pressure losses must be minimized to optimize turbocharger operating flexibility so that the turbine can produce…
The specific objective of this project is to analyze the mechanical and thermodynamic performance of an existing variable geometry turbocharger. This turbocharger, developed by Globe Turbocharger Inc., was built for the 2,000 hp class of…
