  2. 1. Arctic clouds - interactions with radiation and thermodynamic structure

    Author : Joseph Sedlar; Michael Tjernström; Annica Ekman; Johannes Verlinde; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; stratus; radiation; thermodynamic structure; cloud radiative forcing; seasonal transition; Meteorology; Meteorologi; atmosfärvetenskap; Atmospheric Sciences;

    Abstract : Clouds play in important role in the climate system through their interaction with radiation. Globally, clouds tend to cool the Earth by reflecting solar radiation and shading the surface. READ MORE

  4. 2. Thermodynamic analysis of Stirling engine systems : Applications for combined heat and power

    Author : Joseph Adhemar Araoz Ramos; Torsten Fransson; Carlos Augusto Santos Silva; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stirling engine; Thermodynamic analysis; Energiteknik; Energy Technology;

    Abstract : Increasing energy demands and environmental problems require innovative systems for electrical and thermal energy production. In this scenario, the development of small scale energy systems has become an interesting alternative to the conventional large scale centralized plants. READ MORE

  5. 3. Thermodynamic investigations of transition metal systems containing coabon and nitrogen

    Author : Lidong Teng; Seshadri Seetharaman; Tooru Matsumiya; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; thermodynamic activity; galvanic cell technique; transition metal carbides; transition metal nitrides; phase equilibrium; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : In view of the important applications of carbides and carbo-nitrides of transition metals in the heat-resistant and hard materials industries, the thermodynamic activities of Cr and Mn in the Cr-C, Fe-Cr-C, Mn-Ni-C and Mn-Ni-C-N systems have been studied in the present work by the use of the galvanic cell technique. CaF2single crystals were used as the solid electrolyte. READ MORE

  6. 4. Corresponding States Correlations for the Prediction of Thermodynamic Properties of Refrigerants

    Author : Maria Sörner; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; refrigerant mixtures; corresponding states; parameter estimation; equation of state; refrigerants; thermodynamic properties;

    Abstract : When process equipment such as separation units, heat pumps, and refrigeration systems are simulated or designed, physico-chemical properties of the fluids involved must be known. The outcome of the simulation or design depends on the accuracy of the correlations used in the prediction of physico-chemical data, so it is of the utmost importance that the correlations used correctly describe the properties of the fluids.
