Abstract EN
This paper investigate numerically the flow inside an axial turbine of turbocharger in the three dimensions.
The performance of an axial turbine for the turbocharger is heavily affected by blade design due to the flow dynamics in the blade passage.
Furthermore, modification and improvement of a turbine blade is a challenging task for turbomachinery engineers.
Hence, this study is aimed to predict the performance of an axial turbine of automotive engine turbocharger.
A cascade, having nozzle stator, was used for the performance evaluation.
A commercial CFD code ANSYS CFX, was used to simulate the flow and the primary grid generation.
The influence of blade numbers of rotor and stator has been studied by comparing the turbine stage performance.
The results showed that the fluid dynamics within an axial turbine has indicated that the pressure ratio and volume flow rate were predicted.
Obviously, it was observed that the pressure ratio, volume flow rate and efficiency were predicted numerically.
The comparative study of these results indicated noticeable a turbine stage performance.
Overall, numerical results obtained from computational fluid dynamic simulations could produce a much deeper understanding of flow and a highly reliable for estimation on the performance of an axial turbine of turbocharger
