Turbulent Transition In Electromagnetically Levitated Liquid Metal Droplets, Jie Zhao
Turbulent Transition In Electromagnetically Levitated Liquid Metal Droplets, Jie Zhao
Masters Theses
The condition of fluid flow has been proven to have a significant influence on a wide variety of material processes. In electromagnetic levitation (EML) experiments, the internal flow is driven primarily by electromagnetic forces. In 1-g, the positioning forces are very strong and the internal flows are turbulent. To reduce the flows driven by the levitation field, experiments may be performed in reduced gravity and parabolic flights experiments have been adopted as the support in advance. Tracer particles on the surface of levitated droplets in EML experiment performed by SUPOS have been used to investigate the transition from laminar to …
Greening Greenpoint: Investigating Technology And Environment-Based Design, Adam Castelli
Greening Greenpoint: Investigating Technology And Environment-Based Design, Adam Castelli
Masters Theses
This thesis investigates architectural design with a focus on technology and parametric, or computational, design strategies in relation to environmental simulation and sustainability. While numerous studies of new digital and parametric design technologies have been undertaken, few discuss their potential application or synergy with sustainable or environmentally focused design. However, there is increasing interest in bridging the perceived gap between these areas of focus in architectural design, as will be discussed in a section on recent symposia related to performance and design technologies. The research project seeks to apply insight gained from these studies to a design project to be …

Simulation Of An Intake Manifold Pre-Heater For Cold Diesel Engine Startup, Patrick K. Kreun
Masters Theses
Ensuring consistent, reliable diesel engine startups in cold temperatures is of utmost importance in a number of applications. Under extreme temperatures, the use of glow plugs is complemented by intake manifold heaters. In these, the energy released from combustion increases the intake air temperature before the air enters the main combustion chamber. Since the process also alters the stoichiometry of the fuel-air mixture at the intake ports, the preheater operation must be optimized in order to guarantee successful and reliable in-cylinder combustion during engine startups. This paper describes the development of an intake manifold model incorporating an air pre-heater for …
