  1. 1. Thermodynamic properties of humid air and their application in advanced power generation cycles

    Författare :Xiaoyan Ji; Jinyue Yan; Umberto Desideri; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; air-water mixture; humid air; properties; wet cycles; dry air; water; enthalpy; entropy; heat capacity; density; evaporative gas turbine; compressed air energy storage; Chemical engineering; Kemiteknik;

    Sammanfattning : Water or steam is added into the working fluid (often air) in gas turbines to improve the performance of gas turbine cycles. A typical application is the humidified gas turbine that has the potential to give high efficiencies, high specific power output, low emissions and low specific investment. LÄS MER

  2. 2. Creep, deformation and moisture redistribution during air convective wood drying and conditioning : air convective wood drying and conditioning

    Författare :Tom Morén; Luleå tekniska universitet; []

    Sammanfattning : Air convective wood drying is associated with a considerable risk for damage to the timber, especially checking and warping. This thesis contains an analysis of creep and deformation during wood drying related to stress development and susceptibility of checking. Also heat and mass transfer problems in the wood drying process are considered. LÄS MER
