1. 6. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Jonathan Barassa; Rickard Nordlöf; [2020]
   Keywords : Computational Fluid mechanics; Hydropower; Air demand; Free surface flows; ANSYS Fluent;

   Abstract : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. READ MORE

3. 7. Evaluation of drag estimation methods for ship hulls

   University essay from KTH/Mekanik

   Author : Hampus Tober; [2020]
   Keywords : ;

   Abstract : This study aims to evaluate to which degree CFD can complement traditional towing-tank experiments, and to develop a computationally cheap and robust methodology for these type of simulations. Two radically different surface ship hulls were chosen for the trials: a capesize bulk carrier and a fast displacement hull. READ MORE

4. 8. CFD Study of Different Aircraft Cabin Ventilation Systems on Thermal Comfort and Airborne Contaminant Transport : A Study on Passenger Thermal Comfort and Indoor Cabin Air Quality.

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Logeshkumar Srinivasan Venkatesan; Abhishek Raina; [2020]
   Keywords : ;

   Abstract : Aircraft Cabin Ventilation systems are crucial for not only maintaining a fresh supply of air but also help in proper air distribution control and reducing airborne pathogen contamination. Passenger thermal comfort is of vital importance for a comfortable cabin environment and thus the need to measure environmental parameters such as velocity and temperature stratification for different ventilation systems is paramount.

5. 9. Numerical Study on PollutantRemoval Performance of Island Kitchen Exhaust Devices

   University essay from KTH/Byggvetenskap

   Author : Chang Niu; [2019]
   Keywords : Range hoods; kitchen ventilation; indoor air quality; cooking; Köksfläkt; köksventilation; inomhusluftkvalitet; matlagning;

   Abstract : It is reported that cooking can generate many kinds of airborne pollutants,which pose serious threats to human health. Kitchen range-hood is themost effective and popular equipment to exhaust the airborne pollutants,including smoke and oil particle in people’s daily life. READ MORE

6. 10. Sensitivity and Uncertainty Analysis of Building Parameters integrating energy, daylight and thermal comfort

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Tian Tan; Magdalena Szumanska; [2019]
   Keywords : Sensitivity analysis; Uncertainty analysis; Multidisciplinary analysis; Building parameters; Energy consumption; Daylight; Thermal comfort; Optimization; Technology and Engineering;

   Abstract : The objective of this thesis was to perform multidisciplinary sensitivity and uncertainty analysis of the building parameters integrating thermal comfort, energy and daylight. The case study of a Danish office building was used for performing the simulations. READ MORE
