11. Gothenburg District Cooling System - An evaluation of the system performance based on operational data
Abstract : The global energy demand for providing cooling in buildings is expected to increase the next decades, along with a rapid growth in the number of air conditioners and chillers. A more energy efficient, economical and environmentally viable solution to this increased cooling demand, is district cooling. READ MORE

14. Numerical Investigation of Turbulent Fluid Flow and Heat Transfer in Complex Ducts
Abstract : Th need for a reliable and reasonable accurate turbulence model without specific convergence problem for calculating duct flows in industrial applications has become more evident. In this study a general computational method has been developed for calculating turbulent quantities in any arbitrary three dimensional duct. READ MORE
