“…Sakai and al. [18] proposed a novel turbine concept specifically designed for exhausts pulse flow energy conservation and EGR control. In order to combine both these features, an asymmetrically divided double-entry turbine was developed to respond to the imbalance of mass flow due to EGR extraction from one side.…”

This study has highlighted how the needs of drastically reduces carbon, pollutant emissions andenergy recovery in vehicle propulsion systems. The object of this research is to reduce emissions of gaspollutants by investigating the impact of speed and frequency towards the automotive turbocharger. This willdefinitely lead to a reduction in fuel consumption leading to a reduction in the amount of CO2 gas emissions.The present work is conducted with the view to push one step closer towards the full incorporation of thepulsating flow efficiency in the turbine design. In addition, the pulse frequency and the pulsating flowfrequency effects the performances of the turbine are analyzed. The numerical results of the present study arecompared with the experimental data. ANSYS-CFX software is used to solve the equations of a viscous,compressible, highly unsteady and three dimensional turbine inflows. The simulations are conducted at 29,500rpm, 41,500 rpm and 59,740 rpm and respectively at 50%,70% and 100% design speed for both 40 Hz, 56,8 Hzand 80 Hz pulsating flow inlet conditions
