  2. 1. Effective Models for Simulation of Thermal Stratification and Mixing Induced by Steam Injection into a Large Pool of Water

    Author : Hua Li; Pavel Kudinov; Michele Andreani; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermal Stratification; Mixing; Pressure Suppression Pool; Containment; Thermal Hydraulic; GOTHIC; Light Water Reactor; Fysik; Physics;

    Abstract : Steam venting and condensation in a large pool of water creates both a source of heat and a source of momentum. Complex interplay between these two sources leads to either thermal stratification or mixing. READ MORE

  4. 2. Thermal plasticity and limitations in tropical trees

    Author : Maria Wittemann; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acclimation; African tropical forest; chlorophyll fluorescence; climate change; drought; hydraulic; montane; photosynthesis; respiration; successional strategies; temperature; tropical trees; warming;

    Abstract : Tropical forests are the most carbon dense and biodiverse terrestrial biome on earth. In a time of global warming and biodiversity crisis, their preservation must be of high priority. At the same time, they likely operate close to their thermal limits because of a historically and seasonally stable environment. READ MORE

  5. 3. Thermal response test : method development and evaluation

    Author : Signhild Gehlin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

  6. 4. On Model Libraries for Thermo-hydraulic Applications

    Author : Jonas Eborn; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; simulation; Matematik; Automation; Termisk teknik; control systems; nonlinear models; parameter estimation; proces s control; thermo-hydraulic systems; model validation; Thermal engineering; applied thermodynamics; termodynamik; Automatiska system; robotics; control engineering; reglerteknik; robotteknik; Mathematics; object-oriented;

    Abstract : Mathematical modelling and simulation are important tools when dealing with engineering systems that today are becoming increasingly more complex. Tightly integrated production and process optimization are trends that give rise to heterogeneous systems, which are difficult to handle without expertise in several engineering disciplines.

  7. 5. Development and Applications of a General Coupled Thermal-hydraulic/Neutronic Model for the

    Author : Mathias Stålek; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reactor transients; measurements; thermal-hydraulics; core calculations; coupled calculations;

    Abstract : Coupled calculations are important for the simulation of nuclear power plants when there is a strongfeedback between the neutron kineticsand the thermal-hydraulics. A general coupled model of the Ringhals-3 Pressurized Water Reactor has beendeveloped for this purpose. READ MORE
