1. Flow structures in solid-liquid suspensions in mixing and confined jets
Sammanfattning : This thesis investigates the influence of solid particles on different liquid flow systems.Large-scale periodic fluctuations such as macro instability (MI) phenomena in a mixingvessel and jet flows in a confined jet were experimentally analyzed by means of LDV. Theinfluences of different sized (0.5mm-2mm) glass particles (0%vol - 6. LÄS MER
2. Spark Assisted Compression Ignition, SACI
Sammanfattning : The strong focus on decreasing carbon dioxide emissions due to limited natural resources of fossil fuel as well as alarming climate changes drives the research and development of our prime mover, the combustion engine, faster then ever. The minimum requirement is a power source with increased efficiency while emitting ultra low levels of hazardous local and regional emissions. LÄS MER
3. Thermal and Hydraulic Performance of Enhanced Rectangular Tubes for Compact Heat Exchangers
Sammanfattning : The thermal and hydraulic performance of rib-roughened, dimpled and offset strip fin tubes has been investigated experimentally. Results from measurements on commercially manufactured tubes have shown that rib-roughened tubes have best potential for heat transfer enhancement with moderate pressure drop increase. LÄS MER
4. Experimental Studies of Turbulent Mixing in Impinging Jets
Sammanfattning : This thesis concerns the experimental study of mixing and flow characteristic in turbulent circular impinging jets without and with jet orifice manipulators (i.e. passive-fixed perturbations atthe nozzle exit), without and with swirl. LÄS MER
