  2. 1. Thermophysical Properties of Aqueous Solutions Used as Secondary Working Fluids

    Author : Åke Melinder; Björn Palm; Antero Aittomäki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secondary working fluids; secondary refrigerants; indirect systems; aqueous solutions; ice slurry; thermophysical properties; freezing point; density; viscosity; specific heat; thermal conductivity; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Abstract : Secondary working fluids (secondary refrigerants, heat transfer fluids, antifreezes, brines) have long been used in various indirect re-frigeration and heat pump systems. Aqueous solutions (water solu-tions) have long been used as single phase (liquid only) secondary working fluids for cooling in supermarkets, ice rinks, heat recovery systems, heat pumps and other applications.

  5. 3. Design and Construction of Low-Temperature Scanning Tunnelling Microscope for Spectroscopy

    Author : Joakim Lindahl; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mechanical properties; thermophysical properties; stepper motor; ultra-high vacuum; inertial-mass; low temperatures; scanning tunneling microscopy; optical propertie; Fysik; Semiconductory physics; Physics; scanning tunneling luminescence; local probe; photon emission; local carrier injection; Halvledarfysik; Fysicumarkivet A:1998:Lindahl;

    Abstract : This thesis discusses some of the fundamental requirements needed to be fulfilled when constructing a low temperature scanning tunnelling microscope (STM). Three different designs, two non-vacuum and one ultra-high vacuum (UHV), based on either inertial-mass or novel stepper motor principles are presented. READ MORE

  6. 4. 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

  7. 5. Experimental and modelling studies of the thermophysical and thermochemical properties of some slag systems

    Author : Lijun Wang; Seshadri Seetharaman; Kuo-Chih Chou; Miyuki Hayashi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Abstract : In order to optimize the metallurgical processes it is necessary to improve the understandings of the industrial slag properties, which include thermophysical and thermochemical properties. In the present study Mass Triangle Model was applied to predict these properties. READ MORE
