21. Process modeling of liquid composite molding processes
Sammanfattning : The polymer matrix composites (PMCs) are carving out a niche amid the keen market competition to replace the other material counterparts, e.g., metals. Due to the low weight and the corrosion resistance, the PMCs are wildly utilized from aerospace to automobile industries, both in the sectors of civilian and defense. LÄS MER
22. Modeling of aerodynamic particle interaction
Sammanfattning : The purpose of the current study is to investigate the effect of particle-pair interaction for various separation distances and angular positions. The results obtained are used in a particle-laden turbulent jet flows in order to improve the existing Lagrangian Particle Tracking (LPT) models. LÄS MER
23. Structures, Properties and Dynamics of Turbulent Vortices
Sammanfattning : The development of models for several phenomena that occur in turbulent single- and multi-phase flows requires improved descriptions and quantifications of turbulent vortices. In many engineering applications, the time scale of these phenomena is equal to or smaller than the lifetime of turbulent vortices; consequently, they are not adequately described by using average turbulence properties.

24. In Situ Soft X-ray Spectroscopies Applied to Atmospheric Corrosion And Related Systems
Sammanfattning : This thesis concerns the application of various soft x-ray spectroscopic methods (soft x-ray absorption, SXA, and emission, SXE) to complex, non-vacuum compatible systems, including liquids and multi-phase systems. The design, construction, and application of new instrumentation for in situ spectroscopy is described in detail. LÄS MER
25. A Study on Microstructure-Dependent Deformation and Failure Properties of Boron Alloyed Steel
Sammanfattning : Developments in the automotive industry are driven by customer desires and legislative authorities. Legislation has restricted the emissions standards for vehicles, and has mandated the need for higher safety standards. LÄS MER
