  2. 6. Numerical study of interface dynamics and phase change

    Author : Armin Shahmardi; Luca Brandt; Srdjan Sasic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Abstract : Multi-phase fluid flows are ubiquitous in natural phenomena and different industrial applications such as in food industry, the medical sector, heat exchangers, power generation systems, to name a few.  Understanding the underlining  physics of multi-phase flows  proved to be a challenging task due to presence of sophisticated dynamics, including the evolution of the interface between any pair of phases, thermodynamics and possibility of phase change, interactions between the fluid phases and a solid phase, etc. READ MORE

  4. 7. Modeling and analysis of heat and mass transfer processes during in-vessel melt progression stage of light water reactor (LWR) severe accidents

    Author : Robert R. Nourgaliev; KTH; []
    Keywords : ;

    Abstract : The last two decades of nuclear industry are marked byconsiderable attention tonuclear power plant accidents with core meltdown, knownalsoas severe accidents(SA). Two wellknown severeaccidents, TMI (USA, 1979) and Chernobyl (USSR, 1986), igniteda new wave of publit cancern about safety of existing nuclearpower plants. READ MORE

  5. 8. Advanced Gas Turbine Cycles with Water-Air Mixtures as Working Fluid

    Author : Niklas Ågren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas turbine cycles; HAT cycles; evaporative cycles; power generation;

    Abstract : Since the early 80's, the worldwide utilization of gas turbines for thermal power generation has increased rapidly. They have less pollution than any other major combustion energy converters. READ MORE

  6. 9. Assessment and improvements of thermal-hydraulic correlations and methods for the analysis of the Jules Horowitz Reactor

    Author : Alberto Ghione; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Flow instability; Uncertainty; Narrow channels; Jules Horowitz Reactor; Safety analysis; Critical heat flux; Thermal-hydraulic correlations; Heat transfer; Best-Estimate; Material Testing Reactor;

    Abstract : Nuclear research reactors are used to test materials for current and future nuclear technologies, and to produce radioisotopes for medical purposes. Most of the existing Material Testing Reactors in Europe have operated for more than 50 years and new ones are needed. READ MORE

  7. 10. Data-Driven Techniques for Fluid Mechanics and Heat Transfer

    Author : Jerol Soibam; Rebei Bel Fdhila; Konstantinos Kyprianidis; Ioanna Aslanidou; Ricardo Vinuesa Motilva; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Heat Transfer; Machine Learning; Deep Learning; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : One of the main challenges in fluid mechanics and heat transfer is the need for detailed studies andfast computational speed to monitor and optimise a system. These fluid/heat flows comprise time-dependent velocity, multi-scale, pressure, and energy fluctuations. READ MORE
