6. Ventilation of a Model Hydro-Generator, An Experimental and Numerical Study
Sammanfattning : Generators are sophisticated machines used to convert the mechanical energy of a prime mover into electrical energy. Electromagnetic and mechanical losses accompany this energy conversion process. Cooling systems remove the heat, generated by losses, from these machines. LÄS MER
7. Ventilation Flow Field Characteristics of a Hydro-Generator Model- An experimental and Numerical Study
Sammanfattning : Hydro-generators are complex machines used to convert the mechanical energy of the water turbine into electrical energy. Electromagnetic and mechanical losses accompany this energy conversion process which will cause heat generation and temperature increase. Cooling systems are needed to remove this excess heat from hydro-generators. LÄS MER
8. ON THE EFFICIENCY OF DISPLACEMENT VENTILATION, with Particular Reference to the Influence of Human Physical Activity
Sammanfattning : The efficiency of room ventilation by the displacement principle was studied with respect to some influential factors, in particular that of physical activity. The study was experimental and performed in two full-scale test rooms, one of office-size and one of classroom-size. LÄS MER
9. New methods for optimization of mechanical ventilation
Sammanfattning : Mechanical ventilation saves lives, but it is an intervention fraught with the potential for serious complications. Prevention of these complications has become the focus of research and critical care in the last twenty years. LÄS MER
10. Optimization of confluent jets ventilation with variable airflow
Sammanfattning : In recent years, applications of confluent jets for design of ventilation supply devices have been widely studied. Similarly, numerous studies have been made on the potential and application of variable air volume (VAV) in order to reduce the energy demand of ventilation systems. LÄS MER
