With reduced turbo lag and better transient response, the introduction of VTG stator guide vanes improved turbocharger performance at all the engine operating conditions.
The VTG system accelerates and maneuvers exhaust gas flow to the turbine.
Favorable flow conditions at turbine inlet created by vane shape improve turbine performance.
At lower engine speed, it is observed that the pressure drop across vane system influences overall efficiency.
Whereas at higher speed, the pressure drop and guide vane exit flow angle are found to determine the turbine efficiency.
Successful practical operation of VTG system also depends on its ability to smoothly open and close the vanes at different gas loads.
Stator vane shape greatly influences the smooth operability/controllability of vane system.
In the present work, 3 symmetric vanes with different T / C ratios and 2 asymmetric vanes are analyzed.
The effect of geometric changes is studied from overall turbine performance as well as VTG system performance perspective.
It is observed that symmetric vanes cause higher pressure drop at lower speeds leading to lower efficiency irrespective of the vane width.
It is also observed that the pressure drop characteristics and vane exit flow angle are better with the asymmetric vanes, whereas the controllability of symmetric vanes is found to be superior.
Analysis methodology is presented for achieving the best compromise between performance and controllability by the modification of vane geometric parameters through CFD simulations.
