1. Experimental Heat Transfer, pressure drop, and Flow Visualization of R-134a in Vertical Mini/Micro Tubes
Sammanfattning : For the application of minichannel heat exchangers, it is necessary to have accurate design tools for predicting heat transfer and pressure drop. Until recently, this type of heat exchangers was not well studied, and in the scientific literature there were large discrepancies between results reported by different investigators. LÄS MER
2. Numerical Study on Steel Flow and Inclusion Behavior during a Ladle Teeming Process
Sammanfattning : Inclusions in molten steel have received worldwide concern due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the deoxidation process, reoxidation by air and/or slag due to an entrainment during steel transfer, and so on. LÄS MER
3. Modelling of Bingham Suspensional Flow : Influence of Viscosity and Particle Properties Applicable to Cementitious Materials
Sammanfattning : Simulation of fresh concrete flow has spurged with the advent of Self-Compacting Concrete, SCC. The fresh concrete rheology must be compatible with the reinforced formwork geometry to ensure complete and reliable form filling with smooth concrete surfaces. LÄS MER
4. Bio-inspired retinal optic flow perception in robotic navigation
Sammanfattning : This thesis concerns the bio-inspired visual perception of motion with emphasis on locomotion targeting robotic systems. By continuously registering moving visual features in the human retina, a sensation of a visual flow cue is created. An interpretation of visual flow cues forms a low-level motion perception more known as retinal optic flow. LÄS MER
5. Inclusion Motion under a Swirl Flow in the Continuous Casting Process and Wire Feeding in the Induction Furnace
Sammanfattning : The thesis includes the studies of two phenomena related to continuous casting. One subject is the inclusion motion in the submerged entry nozzle (SEN) and mold when using a swirl flow. The swirl flow is generated in a SEN by using an electromagnetic swirl flow generator (EMSFG). LÄS MER
