Variable Geometry Turbine Design for Advanced Turbocharger Application Part 2

Funding body



Principal investigator: Apostolos Pesiridis

Project description

Turbocharger development is perhaps the most crucial area when it comes to automotive industry compliance with ever-increasingly stringent emissions legislation. The gasoline side of the automotive industry has the highest potential both as a market share over that other conventional automotive industry powertrain technology, the diesel engine, but also due to the fact that diesels are 100% turbocharged engines whereas turbocharged gasolines have only recently seen any significant market uptake.

This project is a continuation of the previous EPSRC IAA-sponsored project (“Variable Geometry Turbine Design for Advanced Turbocharger Application”).

The previous project provided early market research, IP state-of-art reporting, conventional design and original design engineering for this new device as well as early computational assessment of its performance.

The Variable Geometry Axial Turbine Turbocharger (VGAT) works as a conventional variable geometry turbine turbocharger (VGT) and carries the traditional benefits of improved car transient response and improved fuel economy but the proposed sliding vane VGAT design is the first design known to be specifically suited to the design characteristics of the axial turbine turbocharger.

In a nutshell the project should lead to:

  • Technological demonstration of VGAT (on standalone turbocharger testing)
  • Early briefing, conference dissemination, marketing and commercialisation material production for VGAT
  • Continued collaboration between Brunel and turbocharger suppliers
  • Additional funding leverage from bodies aimed at both fundamental research and acceleration of impact in the UK automotive sector (e.g. EPSRC, TSB etc)
  • Potential commercialisation (licensing of IP).
Enhanced visibility and attractiveness of Brunel’s already established automotive activities in areas where it wasn’t traditionally involved with until recently (i.e., turbomachine research). /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:8.0pt; mso-para-margin-left:0cm; line-height:107%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-fareast-language:EN-US;}
