    Abstract : Reducing CO2 emissions is one of the key challenges in todays automotive industry. Different strategies to achieve this goal are, for example, to electrify the powertrain and to reduce the aerodynamic drag by reducing the amount of cooling air through the underhood. READ MORE

  7. 5. Aerodynamic Design and Installation Effects of Automotive Electric Cooling Fans

    Author : Debarshee Ghosh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blade Element Momentum BEM ; low-pressure axial fans; electric cooling fans; automotive thermal management; CFD simulations; upstream blockage; fans in parallel;

    Abstract : Electric cooling fans play a crucial role in automotive thermal management. They generate the airflow required for heat rejection from the expended coolant circulating within the heat exchanger. This thesis focuses on the aerodynamic design and installation effects of electric cooling fans or "E-fans". READ MORE
