Effect Of Speeds and Under Inlet Pulsating Flow Conditions onthe Performance ofthe Twin-Entry Mixed Flow Turbine
Authors: , , ,
Abstract: This study has highlighted how the needs of drastically reduces carbon, pollutant emissions and energy recovery in vehicle propulsion systems. The object of this research is to reduce emissions of gas pollutants by investigating the impact of speed and frequency towards the automotive turbocharger. This will definitely 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 the pulsating flow efficiency in the turbine design. In addition, the pulse frequency and the pulsating flow frequency effects the performances of the turbine are analyzed. The numerical results of the present study are compared 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 29,500 rpm, 41,500 rpm and 59,740 rpm and respectively at 50%,70% and 100% design speed for both 40 Hz, 56,8 Hz and 80 Hz pulsating flow inlet conditions.
