11. A new generation of hospital operating room ventilation
Sammanfattning : Surgical site infection is responsible for 38 percent of reported infections after surgery. This infection increases mortality and treatment costs, and prolongs the hospitalization of patients. LÄS MER
12. Air diffusion and solid contaminant behaviour in room ventilation : a CFD based integrated approach
Sammanfattning : One of the most fundamental human needs is fresh air. It has been estimated that people spend comparatively much time in indoor premises. That creates an elevated need for high-quality ventilation systems in buildings. The ventilation airflow rate is recognised as the main parameter for measuring the indoor air quality. LÄS MER
13. Investigations of Flow Patterns in Ventilated Rooms Using Particle Image Velocimetry : Applications in a Scaled Room with Rapidly Varying Inflow and over a Wall-Mounted Radiator
Sammanfattning : This thesis introduces and describes a new experimental setup for examining the effects of pulsating inflow to a ventilated enclosure. The study aimed to test the hypothesis that a pulsating inflow has potential to improve ventilation quality by reducing the stagnation zones through enhanced mixing. LÄS MER
14. On the performance of stratified ventilation
Sammanfattning : People nowadays spend most of their time indoors, for example in their homes, cars, in trains, at work, etc. In Sweden, the energy demand in the built environment is a growing issue. LÄS MER
15. On the efficiency of displacement ventilation
Sammanfattning : The efficiency of room ventilation by the displacementprinciple was studied with respect to some influential factors,in particular that of physical activity. The study wasexperimental and performed in two full-scale test rooms, one ofoffice-size and one of classroom-size. LÄS MER
