  1. 1. Airborne sound insulation of single and double plate constructions

    Författare :Ulrica Kernen; Gudni Jóhannesson; Waldemar Maysenhölder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; : Airborne sound insulation; single plate; double plate; floating-floor; sound reduction index; sound transmission.; Byggnadsteknik; Building engineering; Byggnadsteknik;

    Sammanfattning : The sound insulation demands for dwellings and public building has increased over the years as the number of sound sources has grown. From the outside our homes are exposed to noise from cars, trains, airplanes, etc. Noise intrudes from our neighbours and their television and stereo equipments. LÄS MER

  3. 2. Estimation of Thermal and Hydraulic Characteristics of Compact Brazed Plate Heat Exchangers

    Författare :Vijaya Sekhar Gullapalli; Institutionen för energivetenskaper; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brazed plate heat exchangers; CFD; heat transfer; pressure drop; heat exchanger selection software; transcritical-CO2 calculations; heat exchanger rating; evaporation; condensation; refrigerant properties; discretized calculations;

    Sammanfattning : This thesis work presents various performance estimation methods of compact brazed plate heat exchangers (BPHE) operating in single phase, condenser, evaporator, cascaded and transcritical applications. Such methods play a vital role in development of heat exchanger selection software and during geometry parameter estimation in the new product development process. LÄS MER

  4. 3. On the compression properties of paper - implications for calendering

    Författare :Peter Rättö; KTH; []
    Nyckelord :calendering; compression; creep; density; finite element analysis; heat transfer coefficient; mechanical properties; temperature; thermal conductivity; viscoelasticity; z-direction;

    Sammanfattning : The objective of this work was to study and describe thedeformation of paper in the thickness direction in a calendernip that in some cases was heated. The temperature distributionin the thickness direction was evaluated using modelexperiments. LÄS MER

  5. 4. Aspects of Flexographic Print Quality and Relationship to some Printing Parameters

    Författare :Johanna Johnson; Lars Järnström; Magnus Lestelius; Peter Rättö; Erik Blohm; Jouko Peltonen; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexography; Print Quality; Liner; Board; Newsprint; Water-borne ink; Dynamic Pressure; Plate Properties; Wetting; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Flexographic printing is a common printing method in the packaging field. The printing method is characterized primarily by the flexible printing plate and the low viscosity inks which make it suitable for use on almost any substrate. LÄS MER

  7. 5. On the processing and properties of cellulose-containing polymeric materials

    Författare :Ruth Arino Marine; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological properties; compounding; dispersion; ionic liquids; ethylene-acrylic acid copolymer; cellulose fibres; gels;

    Sammanfattning : ABSTRACTCellulose fibres have properties that make them very attractive as a reinforcement for thermoplastic polymers. Renewability, biodegradability, very good availability and low cost are some general advantages. LÄS MER
