  2. 1. Numerical Analysis of Heat Transfer and Fluid Flow in Heat Exchangers with Emphasis on Pin Fin Technology

    Author : Hamid Nabati; Jafar Mahmoudi; Dan Loyd; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Heat exchanger; Pin fin technology; Cooling system; Power transformers; CO2; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : One of the most important industrial processes is heat transfer, carried out by heat exchangers in single and multiphase flow applications. Despite the existence of well-developed theoretical models for different heat transfer mechanisms, the expanding need for industrial applications requiring the design and optimization of heat exchangers, has created a solid demand for experimental work and effort.

  4. 2. Optimization product parts in high pressure die casting process

    Author : Mohammad Sadeghi; Rebei Bel-fdhila; Dan Loyd; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industriell ekonomi och organisation; Industrial Economics and Organisations;

    Abstract : This thesis describes optimization of die temperature in high pressure die-casting (HPDC) of A380 alloy by experimental observation and numerical simulation with the use of statistical tools. The goal of this research is to determine the optimum die temperature to minimize incidence of these defects and thus maximize production of parts without defects. READ MORE

  5. 3. Application of Parallel Computers to Enhance the Flow Modelling Capability in Aircraft Design

    Author : Mattias Sillén; Dan Loyd; Peter Eliasson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow modelling; parallel computer; parallel efficiency; turbulence modelling; aircraft design; CFD; Fluid mechanics; Strömningsmekanik;

    Abstract : The development process for new aircraft configurations needs to be more efficient in terms of performance, cost and time to market. The potential to influence these factors is highest in early design phases. Thus, high confidence must be established in the product earlier than today. READ MORE
