  2. 1. Thermal physics of asteroids

    Author : Johan S. V. Lagerros; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; asteroids; infrared emission; thermophysical models; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; astronomi; Astronomy;

    Abstract : The thermal infrared and microwave emission from asteroids have many applications. Fundamental physical properties can be investigated, which have implications for the geophysical evolution of the asteroids, and the early history of the solar system.A new thermophysical model of asteroids is presented.

  4. 2. Investigations of thermophysical properties of slags with focus on slag-metal interface

    Author : Luckman Muhmood; Seshadri Seetharaman; Nurni Neelakandan Viswanathan; Allan Cramb; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slags; density; diffusivity; sessile drop; interfacial velocity; interfacial viscosity; interfacial dilatational modulus; interfacial shear viscosity; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The objective of this research work was to develop a methodology for experimentally estimating the interfacial properties at slag-metal interfaces. From previous experiments carried out in the division, it was decided to use surface active elements like sulfur or oxygen to trace any motion at the interface. READ MORE

  5. 3. Impacts of Thermo–Physical Properties on the Design, Operation, and Cost of Monoethanolamine–Based Chemical Absorption

    Author : Worrada Nookuea; Jinyue Yan; Eva Thorin; Hailong Li; Xiaoyan Ji; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The thermodynamic and transport properties of CO2 mixtures are essential to the design, operation, and optimization of all carbon capture and storage processes. To retrieve accurate property values, accurate property models are required. However, there are many properties, which are in turn affected by many factors. READ MORE

  6. 4. Numerical Modelling of Subcooled Nucleate Boiling for Thermal Management Solutions Using OpenFOAM

    Author : Achref Rabhi; Rebei Bel Fdhila; Konstantinos Kyprianidis; Ioanna Aslanidou; Christophe Duwig; Mälardalens universitet; []
    Keywords : Computational Fluid Dynamics; Boiling Flows; Two-phase cooling; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Two-phase cooling solutions employing subcooled nucleate boiling flows e.g. thermosyphons, have gained a special interest during the last few decades. This interest stems from their enhanced ability to remove extremely high heat fluxes, while keeping a uniform surface temperature. READ MORE

  7. 5. Finite temperature properties of elements and alloy phases from first principles

    Author : Hossein Ehteshami; Pavel A. Korzhavyi; Andrei V. Ruban; Tilmann Hickel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials Science and Engineering; Teknisk materialvetenskap; Physics; Fysik;

    Abstract : First principles calculations are usually concerned with properties calculated at temperature 0 K. However, the industrially important materials are functioning at finite temperatures. READ MORE
