  2. 6. Optimization of the Flow Process in Engine Bays - 3D Fan Modeling Strategies

    Author : Peter Gullberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooling; Fan; Aerodynamics; Underhood Thermal Management; CFD;

    Abstract : In todays automotive industry there is an apparent need and demand for low fuel consuming vehicles. This is a fact every automotive OEM is aware of and the heavy duty truck industry is no exception. With a cooling fan in today’s trucks that typically consumes of the order of magnitude 50bHp fully engaged - reducing this loss is very important. READ MORE

  4. 7. 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

  5. 8. A Numerical and Experimental Study of Airflow in Data Centers

    Author : Emelie Wibron; T. Staffan Lundström; Jonathan Lewis Jonathan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Airflow management is crucial for the performance of cooling systems in data centers. The amount of energy consumed by data centers is huge and a large amount is related to the cooling. In attempts to develop energy efficient data centers, numerical methods are important for several reasons. READ MORE

  6. 9. Performance of Compact Heat Exchanger in Non-Perpendicular Cooling Airflows
