TurboMatch from Concepts NREC matches a turbocharger design to the specific engine system by brent haight

Concepts NREC has introduced a new software product designed to fill the engineering design gap between engines and turbochargers. TurboMatch provides an integrated approach to the design and analysis of the complex interaction between the compressor, turbine and other components of a turbocharger and the engine. According to the company, TurboMatch is the first commercially available software that allows advanced compressor and turbine design as part of an overall engine system.

TurboMatch allows users to perform preliminary design of the compressor and turbine in context of a turbocharger system.

Headquartered in Wilder, Vermont, U.S.A., Concepts NREC provides turbomachinery design, engineering services, manufacturing and CAE/CAM software. TurboMatch works in conjunction with Concepts NREC’s Agile Engineering Design System software for turbomachinery design and analysis, and targets OEMs, diesel and gas engine companies and organizations that provide turbocharger design and engineering. “We are essentially adding more of a front end to everything we’ve had before,” said George Zitka, senior sales manager for Concepts NREC.

“This software was developed to fill a need. Turbocharging internal combustion engines is a key technology. With tightening emission regulations, manufacturers are seeing that turbocharging is the way to bring emissions down while still maintaining horsepower. With a turbocharger, you have a compressor and a turbine that are connected by a common shaft so they need to rotate at the same speed. They need to have an accurate transfer of horsepower from one to the other.

“This matching software allows someone to look at it from a higher level and figure out what the turbocharger needs to look like to match the engine properly. But then we take it to the next level by guiding the whole solution into our pre-existing software solution, which then gets into the detail design of what the compressor looks like, for example. In the design mode, users can size the compressor and turbine to meet the required engine size and boost pres-sure, and automatically match the power and rotational speed of the two components,” Zitka said.

According to Zitka, TurboMatch gives anyone responsible for the design, specification or building of turbocharged engines a tool for developing products that meet tightening
emission standards and regulations. It enables users to change compressor and turbine sizes and then predict the effect on the match. It also allows a study of the effect of wastegates, variable geometry, exhaust gas recirculation and component losses on the match and performance.

“Concepts NREC works with all the major turbocharger manufacturers,” said Dr. Nick Baines, distinguished corporate fellow at Concepts NREC. “In talking with our customers, we perceived increasing demand for turbocharger systems that accommodate smaller engine sizes and lower emission standards. There was a missing link between design of a turbocharger and the overall engine system.”
